The radiation generated by a quantum conductor should be correlated with the electrons crossing it. We have measured the correlation between the fluctuations of the high-frequency electromagnetic power generated by a tunnel junction at very low tempe

Quantum entanglement of mechanical systems emerges when distinct objects move with such a high degree of correlation that they can no longer be described separately. Although quantum mechanics presumably applies to objects of all sizes, directly obse

In superconducting quantum computing, qubit state information is conveyed via low-power microwave fields. As such, ultralow-noise microwave amplification plays a central role in measuring these fields to quickly and accurately infer the qubit state.

A well-known component of RF systems is the circulator, a three-port device that allows signals to flow in one direction while inhibiting propagation in the reverse direction. Circulators play an important role in protecting sensitive RF devices from

We present a theoretical model and experimental characterization of a microwave kinetic inductance traveling-wave amplifier (KIT), whose noise performance, measured by a shot-noise tunnel junction (SNTJ), approaches the quantum limit. Biased with a d

The act of observing a quantum object fundamentally perturbs its state, resulting in a random walk toward an eigenstate of the measurement operator. Ideally, the measurement is responsible for all dephasing of the quantum state. In practice, imperfec

We perform the control and readout of a superconducting qubit using microwave signals generated by a high-speed photodiode operating a 20mK. We demonstrate fast single-qubit gates and high-fidelity single-shot readout while maintaining high qubit coh
