Open-source desktop hypervisor with post-quantum disk encryption. Run any OS on any platform, secured with ML-KEM key wrapping and AES-256-GCM.
QuantaBox is a desktop hypervisor that brings post-quantum security to everyday virtualization. Built on QEMU, it uses native hardware acceleration on every platform while encrypting all virtual disk images with AES-256-GCM and ML-KEM-768 (FIPS 203) key wrapping. Whether you are running development environments, testing across operating systems, or isolating sensitive workloads, QuantaBox ensures your VMs are protected against both classical and quantum threats.
QuantaBox includes a built-in ISO library with 40+ curated OS images, smart per-OS VM presets, an in-app noVNC console with SSH access, and encrypted export/import for secure backups. The full CLI provides complete parity with the GUI, making automation and scripting straightforward.
Every virtual disk is encrypted with AES-256-GCM, with keys wrapped using ML-KEM-768 (FIPS 203). Transparent to guest operating systems, active from first boot.
Browse and download from 40+ curated OS images directly within the app. Ubuntu, Fedora, Debian, Windows, FreeBSD, Arch, and many more, all verified and ready to boot.
Automatically selects the best acceleration backend for your platform: KVM on Linux, Hyper-V/WHPX on Windows, Hypervisor.framework on macOS, with TCG software fallback.
Per-OS VM presets configure CPU, memory, disk, and firmware settings automatically. Optimized defaults for each guest OS so you can start working immediately.
Built-in noVNC web console provides instant graphical access to any VM. SSH integration for headless workflows. No external client software required.
Every GUI action is available through the command line. Create, start, stop, snapshot, export, and manage VMs from your terminal or CI/CD scripts.
QuantaBox uses QEMU as its execution engine and selects the optimal hardware acceleration backend for each platform automatically.
| Platform | Acceleration Backend | Notes |
|---|---|---|
| Linux | KVM | Near-native performance with kernel-level virtualization |
| Windows | Hyper-V / WHPX | Windows Hypervisor Platform for hardware-assisted VMs |
| macOS | Hypervisor.framework | Apple's native hypervisor API for Intel and Apple Silicon |
| All platforms | TCG (fallback) | Software emulation when no hardware acceleration is available |
Share directories between host and guest using virtio-9p. Seamless file exchange without network configuration.
Attach host USB devices directly to guest VMs. Supports storage, smart cards, security keys, and other peripherals.
Export and import VMs as encrypted archives. PQ-secured backups that can be safely stored or transferred between machines.
| Component | Minimum | Recommended |
|---|---|---|
| CPU | x86_64 or ARM64 | CPU with VT-x, AMD-V, or Apple Silicon |
| Memory | 4 GB | 16 GB+ |
| Storage | 2 GB (application) | SSD with 100 GB+ free for VM images |
| OS | Windows 10+, Ubuntu 22.04+, macOS 12+ | Latest stable release |
| Acceleration | TCG software fallback | KVM, Hyper-V/WHPX, or Hypervisor.framework |
| Network | Optional | Required for ISO library downloads |
Note: QuantaBox v1.0.0 supports both x86_64 and ARM64 architectures. Hardware acceleration is strongly recommended for production use but not required. The TCG backend provides full software emulation on any supported platform.
QuantaBox v1.0.0 is available for Windows, Linux, and macOS. Download installers, packages, and source code from the documentation portal.
