Organization, Consolidation and Presentation of Financial Statements [Abstract]  
Basis of Presentation
Basis of Presentation
The accompanying unaudited condensed consolidated financial statements of the Company have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information. All intercompany balances and transactions have been eliminated. Certain information and footnote disclosures normally included in annual financial statements have been condensed or omitted. The Company believes the disclosures made are adequate to prevent the information presented from being misleading. However, the accompanying unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included within the Company’s Annual Report
on Form 10-K for the fiscal year ended March 31, 2026 (the “Annual Report”).

The unaudited condensed consolidated interim financial statements reflect all adjustments, consisting only of normal and recurring items, necessary to present fairly our financial position as of September 30, 2026, the results of operations and comprehensive loss, our cash flows, and changes in stockholders’ deficit, as of and for three and six months ended September 30, 2026 and 2025. Interim results are not necessarily indicative of full year performance because of short-term variations.

The condensed consolidated balance sheet at March 31, 2026 was derived from audited financial statements for the year ended March 31, 2026 included in the Annual Report but does not contain all of the footnote disclosures from the annual financial statements.
Reclassifications
Reclassifications
Certain prior-period amounts in the condensed consolidated statements of cash flows have been reclassified to conform to the current period presentation. These reclassifications had no effect on total cash flows.
Use of Estimates
Use of Estimates
The preparation of condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported and disclosed in the condensed consolidated financial statements and accompanying notes. Actual results could differ from these estimates and assumptions due to risks and uncertainties. Such estimates include, but are not limited to, the determination of standalone selling price for revenue arrangements with multiple performance obligations, inventory adjustments, useful lives of intangible assets and property and equipment, stock-based compensation, fair value of warrants, fair value of the Convertible Note and provision for income taxes including related reserves. Management bases its estimates on historical experience and on various other assumptions which management believes to be reasonable, the results of which form the basis for making judgments about the carrying values of assets and liabilities.
Restricted Cash
Restricted Cash
Restricted cash is comprised of bank guarantees and similar required minimum balances that serve as cash collateral in connection with various items including value added taxes, ongoing tax audits and leases in certain countries.
Accounts Receivable and Allowance for Credit Losses
Accounts Receivable and Allowance for Credit Losses
Accounts receivable are recorded at the invoiced amount, and stated at realizable value, net of an allowance for credit losses. The Company maintains an allowance for credit losses for estimated losses based on historical experience and expected collectability of outstanding accounts receivable. The Company performs ongoing credit evaluations of its customers’ financial condition, and for the majority of its customers require no collateral. For customers that do not meet the Company’s credit standards, the Company may require a form of collateral, such as cash deposits or letters of credit, prior to the completion of a transaction. These credit evaluations require significant judgment and are based on multiple sources of information. The Company analyzes such factors as its historical bad debt experience, industry and geographic concentrations of credit risk, current economic trends and changes in customer payment terms. The Company will write-off customer balances in full to the reserve when it has determined that the balance is not recoverable. Changes in the allowance for credit losses are recorded in general and administrative expenses.
The Company has applied the practical expedient, where current conditions that do not affect the historical loss information are taken into account when determining the expected credit loss.
Warrant Accounting
Warrant Accounting
The Company accounts for warrants as either equity-classified or liability-classified instruments based on an assessment of the warrant’s specific terms and applicable authoritative guidance Accounting Standards Codification ("ASC") Topic 480, Distinguishing Liabilities from Equity (“Topic 480”) and ASC Topic 815, Derivatives and Hedging (“Topic 815”). The assessment considers whether the warrants are freestanding financial instruments pursuant to Topic 480, meet the definition of a liability pursuant to Topic 480, and whether the warrants meet all of the requirements for equity classification under Topic 815, including whether the warrants are indexed to the Company’s own common shares and whether the warrant holders could potentially require “net cash settlement” in a circumstance outside of the Company’s control, among other conditions for equity classification. This assessment, which requires the use of professional judgment, is conducted at the time of warrant issuance and as of each subsequent quarterly period end date while the warrants are outstanding.
For issued or modified warrants that meet all of the criteria for equity classification, the warrants are required to be recorded as a component of additional paid-in capital at the time of issuance or modification. For issued or modified warrants that do not meet all the criteria for equity classification, the warrants are required to be recorded at their initial fair value on the date of issuance, and each balance sheet date thereafter. This liability is subject to re-measurement at each balance sheet date until exercised, and any change in fair value is recognized in the Company’s condensed consolidated statements of operations and comprehensive loss. Quantum issued a Conversion Warrant in June 2026 and Forbearance Warrant in September 2025.
Accounting Pronouncements Recently Adopted and Recent Accounting Pronouncements Not Yet Adopted
Accounting Pronouncements Recently Adopted
In July 2025, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2025-05, Financial Instruments—Credit Losses (Topic 326): Measurements of Credit Losses for Accounts
Receivable and Contract Assets. ASU 2025-05 was effective for the Company beginning on April 1, 2026, and did not have a material impact on our financial statement disclosures.
Recent Accounting Pronouncements Not Yet Adopted
In November 2024, the FASB issued ASU 2024-03, Income Statement - Reporting Comprehensive Income -Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses, which requires additional disclosures of specific expense categories included within each expense caption presented on the Statements of Operations. The new standard can be applied on either a fully retrospective or prospective basis. ASU 2024-03 will be effective for our fiscal year beginning April 1, 2027, and interim periods within our fiscal year beginning April 1, 2028, with early adoption permitted. The Company is currently evaluating the impact of this new standard on its financial statement disclosure.

In September 2025, the FASB issued ASU 2025-06, Targeted Improvements to the Accounting for Internal-Use Software” (Topic 350). The updates eliminate references to software development project stages and revises the criteria that must be met to begin capitalizing internal-use software costs. The standard permits entities to adopt the guidance using a prospective, retrospective, or modified transition approach and becomes effective for the Company beginning April 1, 2028, with early adoption permitted. The Company is currently assessing the potential impact that ASU 2025-06 will have on its financial statement disclosures.

In December 2025, the FASB issued ASU 2025-11, Interim Reporting (Topic 270): Narrow-Scope Improvements, which clarifies certain aspects of interim reporting guidance. The standard is effective for interim periods within fiscal years beginning after December 15, 2027, which will be the Company’s fiscal year beginning April 1, 2028, with early adoption permitted. The Company is currently evaluating the impact of this guidance on its interim financial statement disclosures.

In December 2025, the FASB issued ASU 2025-12, Codification Improvements, which amends a broad range of Topics to clarify guidance, correct errors, and make other improvements. The update clarifies that, when an entity reports a loss from continuing operations, it must consider whether instruments that may be settled in cash or shares and are classified as assets or liabilities are dilutive, including the related adjustments to the diluted net loss per share calculation, rather than presuming them to be antidilutive. The amendments to ASC 260 must be applied retrospectively to all periods presented. ASU 2025-12 will be effective for our fiscal year beginning April 1, 2027, including interim periods within that fiscal year, with early adoption permitted. The Company is currently evaluating the impact of this new standard, including the effect on diluted net loss per share related to its liability-classified warrants.
