Our specialized BiasT solution is designed to enable high-fidelity two-qubit gates on flux-tunable superconducting quantum computers. This component provides outstanding linearity and superior noise suppression.

Flux-tunable qubits are highly sensitive to control signal noise, which can be effectively filtered using our BiasT. Additionally, achieving high-fidelity control of qubit frequency requires compensating for the transient response of the control line. This precompensation depends on the system’s linearity, a characteristic that our BiasT ensures. Learn more about the importance of linerarity in our Application Note, see below.

Key perfomance metrics are:

• Highly linear and first-order transfer function
• 10 kHz to 2 GHz frequency range for RF signals
• Low-pass filter for DC with 10 Hz cutoff and 60 dB of suppression up to 1 GHz
• Precision 1 kΩ (±5 ppm/°C) bias resistor for DC path
• Low insertion- and high return-loss (> 16.0 dB)
