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…
Kerr-free three-wave mixing in superconducting quantum circuits
V. V. Sivak, N. E. Frattini, V. R. Joshi +3
Quantum-limited Josephson parametric amplifiers are crucial components in circuit QED readout chains. The dynamic range of state-of-the-art parametric amplifiers is limited by sign…
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…
Optimizing the nonlinearity and dissipation of a SNAIL Parametric Amplifier for dynamic range
N. E. Frattini, V. V. Sivak, A. Lingenfelter +2
We present a new quantum-limited Josephson-junction-based 3-wave-mixing parametric amplifier, the SNAIL Parametric Amplifier (SPA), which uses an array of SNAILs (Superconducting N…
