Non-Markovian Memory Strength Bounds Quantum Process Recoverability
Philip Taranto, Felix A. Pollock, Kavan Modi
Generic non-Markovian quantum processes have infinitely long memory, implying an exact description that grows exponentially in complexity with observation time. Here, we present a…
Resource theories of multi-time processes: A window into quantum non-Markovianity
Graeme D. Berk, Andrew J. P. Garner, Benjamin Yadin +2
We investigate the conditions under which an uncontrollable background processes may be harnessed by an agent to perform a task that would otherwise be impossible within their oper…
An algorithm for solving unconstrained unitary quantum brachistochrone problems
Francesco Campaioli, William Sloan, Kavan Modi +1
We introduce an iterative method to search for time-optimal Hamiltonians that drive a quantum system between two arbitrary, and in general mixed, quantum states. The method is base…
General anesthesia reduces complexity and temporal asymmetry of the informational structures derived from neural recordings in Drosophila
Roberto N. Muñoz, Angus Leung, Aidan Zecevik +5
We apply techniques from the field of computational mechanics to evaluate the statistical complexity of neural recording data from fruit flies. First, we connect statistical comple…
Equilibration on average in quantum processes with finite temporal resolution
Pedro Figueroa-Romero, Kavan Modi, Felix A. Pollock
We characterize the conditions under which a multi-time quantum process with a finite temporal resolution can be approximately described by an equilibrium one. By providing a gener…
Non-Markovian memory in IBMQX4
Joshua Morris, Felix A. Pollock, Kavan Modi
We measure and quantify non-Markovian effects in IBM's Quantum Experience. Specifically, we analyze the temporal correlations in a sequence of gates by characterizing the performan…
Exploiting the causal tensor network structure of quantum processes to efficiently simulate non-Markovian path integrals
Mathias R. Jørgensen, Felix A. Pollock
In the path integral formulation of the evolution of an open quantum system coupled to a Gaussian, non-interacting environment, the dynamical contribution of the latter is encoded…
Completely Positive Divisibility Does Not Mean Markovianity
Simon Milz, M. S. Kim, Felix A. Pollock +1
In the classical domain, it is well-known that divisibility does not imply that a stochastic process is Markovian. However, for quantum processes, divisibility is often considered…
