Measurements with randomly chosen settings determine many important properties of
quantum states without the need for a shared reference frame or calibration. They naturally …

We report a proof-of-concept demonstration of a quantum order-finding algorithm for
factoring the integer 21. Our demonstration involves the use of a compiled version of the …

As quantum technologies advance, the ability to generate increasingly large quantum states
has experienced rapid development. In this context, the verification and estimation of large …

We present an approach to estimate the operational distinguishability between an entangled
state and any separable state directly from measuring an entanglement witness. We show …

Many-body quantum systems can be characterized using the notions of k-separability and
entanglement depth. A quantum state is k-separable if it can be expressed as a mixture of k …

Quantum entanglement is usually revealed via a well aligned, carefully chosen set of
measurements. Yet, under a number of experimental conditions, for example in …

Entanglement is one of the most studied properties of quantum mechanics for its application
in quantum information protocols. Nevertheless, detecting the presence of entanglement in …

Many future quantum technologies rely on the generation of entangled states. Quantum
devices will require verification of their operation below some error threshold, but the …

Einstein-Podolsky-Rosen (EPR) steering, a category of quantum nonlocal correlations
describing the ability of one observer to influence another party's state via local …

Recently, there are tremendous developments on the number of controllable qubits in
several quantum computing systems. For these implementations, it is crucial to determine …
