Recently, there has been much interest in a new kind of “unspeakable” quantum information
that stands to regular quantum information in the same way that a direction in space or a …

Quantum neural network architectures that have little to no inductive biases are known to
face trainability and generalization issues. Inspired by a similar problem, recent …

Contemporary quantum computers have relatively high levels of noise, making it difficult to
use them to perform useful calculations, even with a large number of qubits. Quantum error …

The inevitable accumulation of errors in near-future quantum devices represents a key
obstacle in delivering practical quantum advantages, motivating the development of various …

The usual way to reveal properties of an unknown quantum state, given many copies of a
system in that state, is to perform measurements of different observables and to analyse the …

The permutational invariance of identical two-level systems allows for an exponential
reduction in the computational resources required to study the Lindblad dynamics of …

We discuss encodings of fermionic many-body systems by qubits in the presence of
symmetries. Such encodings eliminate redundant degrees of freedom in a way that …

We propose GM-QAOA, a variation of the Quantum Alternating Operator Ansatz (QAOA) that
uses Grover-like selective phase shift mixing operators. GM-QAOA works on any NP …

Superposition and entanglement, the quintessential characteristics of quantum physics,
have been shown to provide communication, computation, and sensing capabilities that go …
