Alquor 2.0

Run more experiments.
Iterate faster.

Quantum optics research is advancing at enormous speed — but lab infrastructure is becoming the bottleneck: today's experiments often depend on complex optical-table setups, manual alignment, limited repeatability and long setup cycles.

Alquor 2.0 bridges the gap between what research demands and what existing lab infrastructure can deliver, providing a platform for programmable linear optics experimentation.

Faster Experiment Cycles
Reconfigure the photonic circuit in software. Hours become minutes.
Programmable Transformations
Implement any arbitrary unitary on up to 32 optical channels.
Higher Repeatability
Calibrated, thermally stabilized PIC delivers consistent results.
Reduced Setup Complexity
Plug in, calibrate once, run experiments — no alignment expertise.
Pathway to Photonic QC
Supports MBQC, boson sampling, quantum walks and LOQC research.

Alquor 2.0 integrates seamlessly with your photonic experiment infrastructure, combining integrated photonics, control and lab usability.

The recommended equipment to run experiments on Alquor comprises fiber-coupled light sources (single-photon sources, CW lasers, etc.), a demultiplexing mechanism (a DMUX or fiber switch), a phase locking system (if required for the experiment) and a detection system (PD arrays, SNSPDs, Time Tagger, etc.).

From Optical-Table complexity to Integrated Precision.
