Fast simulation of bosonic qubits via Gaussian functions in phase space

Understand

Bosonic qubits are a promising route to building fault-tolerant quantum computers on a variety of physical platforms.

• Studying the performance of bosonic qubits under realistic gates and measurements is challenging with existing analytical and numerical tools.
• We present a novel formalism for simulating classes of states that can be represented as linear combinations of Gaussian functions in phase space.
• This formalism allows us to analyze and simulate a wide class of non-Gaussian states, transformations and measurements.
