Fast and high-fidelity qubit readout in the microwave domain
The RTX BBN WB-JPA is available as the only off-the-shelf component of its kind and can be easily acquired through Raytheon BBN’s distributor Quantum Microwave.
Key Capabilities
Designed for use at millikelvin temperatures, the amplifier features over 20dB of gain with a center frequency that can be tuned with an on-chip bias line. The amplifier can be operated in either four-wave mixing, or three-wave mixing with an external bias tee.
Benefits
- Improved qubit readout fidelity, reduced noise < 300 mK @ 6.8GHz
- Large bandwidth supports multiplexed readout
- Simple tune-up and low insertion loss for easy integration with qubit experiments
