Experimental signatures of a beam-splitter interaction between Kerr-cat and transmon qubits
Josiah Cochran, Haley M. Cole, Hebah Goderya +5
Quantum error correction (QEC) requires ancilla qubits to extract error syndromes from data qubits which store quantum information. However, ancilla errors can propagate back to th…
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…
Cavity Attenuators for Superconducting Qubits
Z. Wang, S. Shankar, Z. K. Minev +3
Dephasing induced by residual thermal photons in the readout resonator is a leading factor limiting the coherence times of qubits in the circuit QED architecture. This residual the…
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…
Generation of discord through a remote joint continuous variable measurement
E. Zalys-Geller, A. Narla, S. Shankar +5
In quantum mechanics, continuously measuring an observable steers the system into one eigenstate of that observable. This property has interesting and useful consequences when the…
Continuous quantum nondemolition measurement of the transverse component of a qubit
U. Vool, S. Shankar, S. O. Mundhada +9
Quantum jumps of a qubit are usually observed between its energy eigenstates, also known as its longitudinal pseudo-spin component. Is it possible, instead, to observe quantum jump…
