Observation of quantum state collapse and revival due to the single-photon Kerr effect
Gerhard Kirchmair, Brian Vlastakis, Zaki Leghtas +7
Photons are ideal carriers for quantum information as they can have a long coherence time and can be transmitted over long distances. These properties are a consequence of their we…
Hardware-efficient autonomous quantum error correction
Zaki Leghtas, Gerhard Kirchmair, Brian Vlastakis +3
We propose a new method to autonomously correct for errors of a logical qubit induced by energy relaxation. This scheme encodes the logical qubit as a multi-component superposition…
Deterministic protocol for mapping a qubit to coherent state superpositions in a cavity
Zaki Leghtas, Gerhard Kirchmair, Brian Vlastakis +3
We introduce a new gate that transfers an arbitrary state of a qubit into a superposition of two quasi-orthogonal coherent states of a cavity mode, with opposite phases. This qcMAP…
Black-box superconducting circuit quantization
Simon E. Nigg, Hanhee Paik, Brian Vlastakis +6
We present a semi-classical method for determining the effective low-energy quantum Hamiltonian of weakly anharmonic superconducting circuits containing mesoscopic Josephson juncti…
