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…
Free-standing silicon shadow masks for transmon qubit fabrication
I. Tsioutsios, K. Serniak, S. Diamond +6
Nanofabrication techniques for superconducting qubits rely on resist-based masks patterned by electron-beam or optical lithography. We have developed an alternative nanofabrication…
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…
Direct Dispersive Monitoring of Charge Parity in Offset-Charge-Sensitive Transmons
K. Serniak, S. Diamond, M. Hays +5
A striking characteristic of superconducting circuits is that their eigenspectra and intermode coupling strengths are well predicted by simple Hamiltonians representing combination…
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…
