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…
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…
The Kerr-Cat Qubit: Stabilization, Readout, and Gates
Alexander Grimm, Nicholas E. Frattini, Shruti Puri +6
Quantum superpositions of macroscopically distinct classical states, so-called Schrödinger cat states, are a resource for quantum metrology, quantum communication, and quantum comp…
Bias-preserving gates with stabilized cat qubits
Shruti Puri, Lucas St-Jean, Jonathan A. Gross +9
The code capacity threshold for error correction using qubits which exhibit asymmetric or biased noise channels is known to be much higher than with qubits without such structured…
