Tynana builds programmable control infrastructure for superconducting quantum systems. We distribute shared optical pulse envelopes and apply cryogenic local correction to reduce per-channel waveform generation, memory, wiring, and heat.
Pre-product. Pre-revenue. Building toward a first small multi-channel prototype. Analytical estimates and prototype validation are in progress.
Superconducting qubits are controlled by microwave pulses, but scaling the control layer is becoming a physical bottleneck: wiring, memory, high-speed waveform generation, and cryogenic power all grow in the wrong direction.
Conventional RF racks and coaxial wiring provide high-quality control, but they scale with cables, instruments, and thermal load.
Putting electronics in the fridge helps wiring, but per-channel high-speed DACs, waveform memory, and RF generation remain expensive in power.
Optical links reduce thermal wiring load, but large-scale systems still need local calibration, gating, timing, and per-channel correction.
Tynana separates quantum control into layers. The expensive waveform generation is shared. The cryogenic endpoint only applies the local correction needed for each qubit channel.
We are changing what has to happen locally. Instead of generating a complete high-speed waveform per qubit channel at cryogenic temperature, we distribute shared pulse envelopes and apply low-power local correction.
The local DAC is a coefficient, not a waveform generator.
Store calibration parameters instead of full waveform data.
Per-channel amplitude, gating, timing, and calibration updates.
First-order model targets sub-mW/channel at 4K for the integration prototype.
Our first prototype path uses GF45SPCLO because it can place silicon photonics, Ge photodiodes, and CMOS local correction in one integration-friendly platform.
This is not the final lowest-power platform. It is the fastest way to validate the control mechanism: a shared optical Gaussian envelope, a local transmission coefficient, photodiode recovery, and low-power CMOS correction.
The long-term route targets TFLN photonic distribution, InGaAs detection, and GF 22FDX cryogenic CMOS.
See platform roadmap →GF45SPCLO, O-band SiPh, Ge PD, local CMOS coefficient control, and PCB-level BPF for LO selection.
Shared optical pulse distribution, local amplitude scaling, photodetection, and correction without per-channel waveform generation.
It does not claim full qubit control, full product readiness, or final TFLN performance.
The first job is to de-risk the architecture. Demo first, product later.
We want to talk to labs, startups, and hardware teams running into control power, wiring, calibration, or cryogenic integration limits.
Tynana is an early-stage quantum control infrastructure company founded by Bowen Liu and Peter Zhang. We are pre-product and pre-revenue, focused on validating a specific architecture for scalable superconducting-qubit control.
The company’s first priority is not to build qubits, sell foundry services, or claim a full quantum computer. It is to prove that shared photonic distribution plus cryogenic local correction can reduce the cost of controlling many qubits.
