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…
Reference-State Error Mitigation: A Strategy for High Accuracy Quantum Computation of Chemistry
Phalgun Lolur, Mårten Skogh, Christopher Warren +6
Decoherence and gate errors severely limit the capabilities of state-of-the-art quantum computers. This work introduces a strategy for reference-state error mitigation (REM) of qua…
