Quantum Control Infrastructure

Low-power control
for scalable
quantum computers.

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.

The Bottleneck

Quantum systems can fabricate more qubits than they can efficiently control.

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.

01

RF control is programmable, but heavy.

Conventional RF racks and coaxial wiring provide high-quality control, but they scale with cables, instruments, and thermal load.

02

Cryo-CMOS moves closer, but still generates waveforms.

Putting electronics in the fridge helps wiring, but per-channel high-speed DACs, waveform memory, and RF generation remain expensive in power.

03

Pure photonic links distribute well, but correct poorly.

Optical links reduce thermal wiring load, but large-scale systems still need local calibration, gating, timing, and per-channel correction.

Our Approach

Shared signals. Local 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.

What Makes Us Different

We do not try to build a better RF rack.

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.

No
High-speed waveform DAC per channel

The local DAC is a coefficient, not a waveform generator.

Less
Cryogenic waveform memory

Store calibration parameters instead of full waveform data.

Local
Programmable correction

Per-channel amplitude, gating, timing, and calibration updates.

Sub-mW
Prototype power target

First-order model targets sub-mW/channel at 4K for the integration prototype.

Note: Power numbers are analytical projections for the first prototype, not measured product claims. Experimental validation is pending. Current estimates depend on photodiode responsivity, MZI insertion loss, TIA power, and local correction circuitry.
First Prototype

Integration-first, not final-product-first.

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.

Current prototype path

GF45SPCLO, O-band SiPh, Ge PD, local CMOS coefficient control, and PCB-level BPF for LO selection.

What the demo proves

Shared optical pulse distribution, local amplitude scaling, photodetection, and correction without per-channel waveform generation.

What it does not claim

It does not claim full qubit control, full product readiness, or final TFLN performance.

Why this is enough

The first job is to de-risk the architecture. Demo first, product later.

Collaborate

Working on superconducting quantum hardware?

We want to talk to labs, startups, and hardware teams running into control power, wiring, calibration, or cryogenic integration limits.

Company

Early, focused, and technical.

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.
