The Gain-Engineered Transmon
Ian Yang, Francesco Adinolfi, Alessandro Bruno +3
The interaction between a qubit and its environment can be engineered such that one error channel dominates over all others, resulting in noise bias. This property enables error co…
Quantum theory of a three-photon Kerr parametric oscillator
Alessandro Bruno, Patrick P. Potts, Alexander Grimm +1
We investigate the quantum properties of a nonlinear Kerr oscillator driven by a three-photon pump. We derive both exact and approximate analytical expressions for the ground state…
Enhancing Kerr-Cat Qubit Coherence with Controlled Dissipation
Francesco Adinolfi, Daniel Z. Haxell, Alessandro Bruno +4
Quantum computing crucially relies on maintaining quantum coherence for the duration of a calculation. Bosonic quantum error correction protects this coherence by encoding qubits i…
Experimental implementation of a Raman-assisted six-quanta process
S. O. Mundhada, A. Grimm, J. Venkatraman +9
Nonlinear processes in the quantum regime are essential for many applications, such as quantum-limited amplification, measurement and control of quantum systems. In particular, the…
Gated conditional displacement readout of superconducting qubits
S. Touzard, A. Kou, N. E. Frattini +6
We have realized a new interaction between superconducting qubits and a readout cavity that results in the displacement of a coherent state in the cavity, conditioned on the state…
Coherent oscillations inside a quantum manifold stabilized by dissipation
S. Touzard, A. Grimm, Z. Leghtas +13
Manipulating the state of a logical quantum bit usually comes at the expense of exposing it to decoherence. Fault-tolerant quantum computing tackles this problem by manipulating qu…
