Energy-participation quantization of Josephson circuits
Zlatko K. Minev, Zaki Leghtas, Shantanu O. Mundhada +3
Superconducting microwave circuits incorporating nonlinear devices, such as Josephson junctions, are one of the leading platforms for emerging quantum technologies. Increasing circ…
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…
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…
To catch and reverse a quantum jump mid-flight
Z. K. Minev, S. O. Mundhada, S. Shankar +6
Quantum physics was invented to account for two fundamental features of measurement results -- their discreetness and randomness. Emblematic of these features is Bohr's idea of qua…
