Abstract

A non-linear superconducting quantum circuit (1) including a memory mode (3), a buffer mode (5), a SNAIL (7) coupled to both the memory mode (3) and the buffer mode (5), a SNAIL flux line (9) inductively coupled to the SNAIL (7), and a DC SQUIDs flux line (11) inductively coupled to a tunable inductive element (21). The non-linear superconducting quantum circuit (1) is configured to operate in: • a resonant dissipative mode in which the SNAIL flux line (9) causes the SNAIL (7) to implement three-wave mixing between the memory mode (3) and the buffer mode (5), and the DC SQUIDs flux line (11) varies the buffer resonant frequency to be equal to twice the memory resonant frequency, and • a Kerr Hamiltonian mode in which the SNAIL flux line (9) causes the SNAIL (7) to implement four-wave mixing between the memory mode (3) and the buffer mode (5).
