Quantum Chaos is Quantum [PDF]
It is well known that a quantum circuit onNqubits composed of Clifford gates with the addition ofknon Clifford gates can be simulated on a classical computer by an algorithm scaling aspoly(N)exp(k)\cite{bravyi2016improved}. We show that, for a quantum circuit to simulate quantum chaotic behavior, it is both necessary and sufficient thatk=Θ(N).

Degree of Quantumness in Quantum Synchronization [PDF]
AbstractWe introduce the concept of degree of quantumness in quantum synchronization, a measure of the quantum nature of synchronization in quantum systems. Following techniques from quantum information, we propose the number of non-commuting observables that synchronize as a measure of quantumness.

The Fundamental Nature of Motives
Decision-making is described as a natural process, one among others, consuming free energy in the least time. The thermodynamic tenet explains why data associated with decisions display the same patterns as any other data: skewed distributions, sigmoidal

Quantumness of quantum channels [PDF]
Quantum coherence is a fundamental aspect of quantum physics and plays a central role in quantum information science. This essential property of the quantum states could be fragile under the influence of the quantum operations. The extent to which quantum coherence is diminished depends both on the channel and the incoherent basis.

Quantum computing for quantum tunneling [PDF]
We demonstrate how quantum field theory problems can be embedded on quantum annealers. The general method we use is a discretisation of the field theory problem into a general Ising model, with the continuous field values being encoded into Ising spin chains.

QUANTUM ESPRESSO: a modular and open-source software project for quantum simulations of materials [PDF]
QUANTUM ESPRESSO is an integrated suite of computer codes for electronic-structure calculations and materials modeling, based on density-functional theory, plane waves, and pseudopotentials (norm-conserving, ultrasoft, and projector-augmented wave).
