Three-wave mixing traveling-wave parametric amplifier with periodic variation of the circuit parameters

Anita Fadavi Roudsari, Daryoush Shiri, Hampus Renberg Nilsson +8

We report the implementation of a near-quantum-limited, traveling-wave parametric amplifier that uses three-wave mixing (3WM). To favor amplification by 3WM, we use the superconduc…

Transmon qubit readout fidelity at the threshold for quantum error correction without a quantum-limited amplifier

Liangyu Chen, Hang-Xi Li, Yong Lu +17

High-fidelity and rapid readout of a qubit state is key to quantum computing and communication, and it is a prerequisite for quantum error correction. We present a readout scheme f…

Extensive characterization of a family of efficient three-qubit gates at the coherence limit

Christopher W. Warren, Jorge Fernández-Pendás, Shahnawaz Ahmed +13

While all quantum algorithms can be expressed in terms of single-qubit and two-qubit gates, more expressive gate sets can help reduce the algorithmic depth. This is important in th…

Measurement and control of a superconducting quantum processor with a fully-integrated radio-frequency system on a chip

Mats O. Tholén, Riccardo Borgani, Giuseppe Ruggero Di Carlo +8

We describe a digital microwave platform called Presto, designed for measurement and control of multiple quantum bits (qubits) and based on the third-generation radio-frequency sys…

Simultaneous bistability of qubit and resonator in circuit quantum electrodynamics

Th. K. Mavrogordatos, G. Tancredi, M. Elliott +6

We explore the joint activated dynamics exhibited by two quantum degrees of freedom: a cavity mode oscillator which is strongly coupled to a superconducting qubit in the strongly c…
