The trend of today's electronic developments is the reduction of essential devices and the
expansion of their functionality. This creates a demand for new nano-elements that can …

Continuously monitoring the environment of a quantum many-body system reduces the
entropy of (purifies) the reduced density matrix of the system, conditional on the outcomes of …

The quantum computing devices of today have tens to hundreds of qubits that are highly
susceptible to noise due to unwanted interactions with their environment. The theory of …

A bstract Entanglement entropy, or von Neumann entropy, quantifies the amount of
uncertainty of a quantum state. For quantum fields in curved space, entanglement entropy of …

The thermal or equilibrium ensemble is one of the most ubiquitous states of matter. For
models comprised of many locally interacting quantum particles, it describes a wide range of …

Quantum signal processing (QSP) represents a real scalar polynomial of degree $ d $ using
a product of unitary matrices of size $2\times 2$, parameterized by $(d+ 1) $ real numbers …

Does gravity constrain computation? We study this question using the AdS/CFT
correspondence, where computation in the presence of gravity can be related to non …

There is a folkloric belief that a depth-$\Theta (m) $ quantum circuit is needed to estimate the
trace of the product of $ m $ density matrices (ie, a multivariate trace), a subroutine crucial to …

The Internet of Things (IoT) strongly influences the world economy; this emphasizes the
importance of securing all four aspects of the IoT model: sensors, networks, cloud, and …

For two unknown mixed quantum states and in an-dimensional Hilbert space, computing
their fidelity is a basic problem with many important applications in quantum computing and …
