Ordering Matters: Structure, Accuracy and Gate Cost in Second-Order Suzuki Product Formulas
Matthew A Lane, Dan E Browne
Product formula methods, particularly the second-order Suzuki decomposition, are an important tool for simulating quantum dynamics on quantum computers due to their simplicity and…

Efficient choice of coloured noises in stochastic dynamics of open quantum systems
Daniel Matos, Matthew A Lane, Ian J Ford +1
The Stochastic Liouville-von Neumann (SLN) equation describes the dynamics of an open quantum system reduced density matrix coupled to a non-Markovian harmonic environment. The int…

Exactly Thermalised Quantum Dynamics of the Spin-Boson Model coupled to a Dissipative Environment
M. A. Lane, D. Matos, I. J. Ford +1
We present an application of the Extended Stochastic Liouville-von Neumann equations (ESLN) method introduced earlier [PRB 95, 125124 (2017); PRB 97, 224310 (2018)] which describes…
