Bridging Entanglement and Magic Resources within Operator Space
Neil Dowling, Kavan Modi, Gregory A. L. White
Local-operator entanglement (LOE) dictates the complexity of simulating Heisenberg evolution using tensor network methods, {and bears witness to many-body chaos for local dynamics}…
Tensor-network decoders for process tensor descriptions of non-Markovian noise
Fumiyoshi Kobayashi, Hidetaka Manabe, Gregory A. L. White +3
Quantum error correction (QEC) is essential for fault-tolerant quantum computation. Often in QEC errors are assumed to be independent and identically distributed and can be discret…
Practical learning of multi-time statistics in open quantum systems
Gregory A. L. White, Lloyd C. L. Hollenberg, Charles D. Hill +1
Randomised measurements can efficiently characterise many-body quantum states by learning the expectation values of observables with low Pauli weights. In this paper, we generalise…
Many-time physics in practice: characterising and controlling non-Markovian quantum stochastic processes
Gregory A. L. White
Every year, substantial theoretical and experimental progress is made towards the realisation of a genuinely new computational paradigm in the construction of a quantum computer. B…
Randomised benchmarking for characterizing and forecasting correlated processes
Xinfang Zhang, Zhihao Wu, Gregory A. L. White +12
The development of fault-tolerant quantum processors relies on the ability to control noise. A particularly insidious form of noise is temporally correlated or non-Markovian noise.…
Unifying non-Markovian characterisation with an efficient and self-consistent framework
Gregory A. L. White, Petar Jurcevic, Charles D. Hill +1
Noise on quantum devices is much more complex than it is commonly given credit. Far from usual models of decoherence, nearly all quantum devices are plagued both by a continuum of…
Topological Signal Processing on Quantum Computers for Higher-Order Network Analysis
Caesnan M. G. Leditto, Angus Southwell, Behnam Tonekaboni +3
Predicting and analyzing global behaviour of complex systems is challenging due to the intricate nature of their component interactions. Recent work has started modelling complex s…
Capturing long-range memory structures with tree-geometry process tensors
Neil Dowling, Kavan Modi, Roberto N. Muñoz +2
We introduce a class of quantum non-Markovian processes -- dubbed process trees -- that exhibit polynomially decaying temporal correlations and memory distributed across time scale…
