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
  • Parallelized gate execution and atom transport

Applications

Quantum cryptography with BTQ Technologies

QPerfect works closely with BTQ Technologies, its parent company, 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.
