Fault-Tolerant Compilation

Quantum Logic Unit: from algorithm to fault‑tolerant hardware

QLU™ is a fault‑tolerant compiler with hardware-specific QEC and a real-time syndrome decoder, engineered for the emerging class of neutral-atom quantum processors.

Key capabilities

End-to-end fault-tolerant middleware purpose-built for neutral atom quantum processors.

Fault-Tolerant Compiler

Compiles quantum circuits into fault-tolerant circuits with quantum error correction, magic state distillation, and loss detection.

Hardware-Specific Optimization

Tailors execution for neutral atom QPUs: zoned architectures, native gate sets (RX, RZ, CZ), and atom movement scheduling.

Real-Time Error Decoder

On-the-fly quantum error correction decoding for continuous fault-tolerant operation during circuit execution.

Secure Cloud QDK

Quantum Development Kit with secure cloud access for remote circuit design, compilation, and execution management.

From quantum algorithm to neutral-atom hardware

QLU™ is a multi-stage compilation and error-correction pipeline that takes a high-level quantum algorithm down to scheduled hardware instructions, with continuous decoder feedback at execution time.

QLU™ is QPerfect’s proprietary fault-tolerant compilation and error-correction stack, engineered for the emerging class of neutral-atom quantum processors. Its design targets architectural patterns now common across the field: zoned layouts with dedicated entangling, readout, and storage regions; programmable connectivity via atom transport; long-coherence atomic species.

These shared design targets unlock optimization opportunities unavailable to generic compilers:

  • QLDPC code connectivity matched to native neutral-atom interactions
  • Subroutine-to-zone mapping for minimal atom movement
  • Space-time scheduling across parallel execution zones
  • Adaptive QEC rounds based on real-time error rates
  • Parallelised gate execution and atom transport

Applications

Quantum cryptography with BTQ Technologies

QPerfect works closely with BTQ Technologies (the company set to become QPerfect’s parent following its announced acquisition) to deliver a quantum advantage for cryptographic applications on neutral-atom hardware. QLU™ compiles and optimizes BTQ’s One-Shot Signatures (OSS) protocol for fault-tolerant execution: an unforgeable, single-use digital signature scheme that relies on the physics of quantum measurement for its security guarantees.

QLU™ + MIMIQ™: Design, validate, execute

MIMIQ™’s digital twin validates fault-tolerant circuit designs before QLU™ executes them on real hardware. Hardware-accurate noise models ensure that what you simulate is what you get, closing the loop between algorithm design and physical execution.

Design with MIMIQ™

Develop and test quantum algorithms at scale using MIMIQ™'s statevector and MPS engines before committing to hardware.

Validate with Digital Twin

Simulate fault-tolerant circuits with hardware-accurate noise models to predict real-device performance before execution.

Execute with QLU™

Compile validated circuits to fault-tolerant hardware instructions and run on neutral atom quantum processors.
