Sequential quantum simulation of spin chains with a single circuit QED device
Yuxuan Zhang, Shahin Jahanbani, Ameya Riswadkar +2
Quantum simulation of many-body systems in materials science and chemistry are promising application areas for quantum computers. However, the limited scale and coherence of near-t…
Fully Directional Quantum-limited Phase-Preserving Amplifier
Gangqiang Liu, Andrew Lingenfelter, Vidul R. Joshi +4
We present a way to achieve fully directional, quantum-limited phase-preserving amplification in a four-port, four-mode superconducting Josephson circuit by utilizing interference…
Quantum Microwave Radiometry with a Superconducting Qubit
Zhixin Wang, Mingrui Xu, Xu Han +6
The interaction of photons and coherent quantum systems can be employed to detect electromagnetic radiation with remarkable sensitivity. We introduce a quantum radiometer based on…
Josephson Array Mode Parametric Amplifier
V. V. Sivak, S. Shankar, G. Liu +2
We introduce a novel near-quantum-limited amplifier with a large tunable bandwidth and high dynamic range - the Josephson Array Mode Parametric Amplifier (JAMPA). The signal and id…
Quantum error correction of a qubit encoded in grid states of an oscillator
P. Campagne-Ibarcq, A. Eickbusch, S. Touzard +10
Quantum bits are more robust to noise when they are encoded non-locally. In such an encoding, errors affecting the underlying physical system can then be detected and corrected bef…
Quantum back-action of variable-strength measurement
M. Hatridge, S. Shankar, M. Mirrahimi +9
Measuring a quantum system can randomly perturb its state. The strength and nature of this back-action depends on the quantity which is measured. In a partial measurement performed…
