Exceptional points (EPs) of non-Hermitian (NH) systems have recently attracted increasing
attention due to their rich phenomenology and intriguing applications. Compared to the …

We propose a novel algorithm for quantum spatial search on a star graph using interleaved
continuous-time quantum walks and marking oracle queries. Initializing the system in the …

Quantum metrology overcomes standard precision limits and plays a central role in science
and technology. Practically, it is vulnerable to imperfections such as decoherence. Here we …

The application of quantum algorithms has attracted much attention as it holds the promise
of solving practical problems that are intractable to classical algorithms. One such …

We consider two different types of conditions which were proposed to test macrorealism in
the context of a system described by a single dichotomic variable Q. This is the view that a …

Experimental validation and control of quantum traits for an open quantum system are
important for any quantum information purpose. We consider a traveling atom qubit as a …

Contextuality is a phenomenon at the heart of quantum mechanics different from classical
behavior and has been recently identified as a resource in quantum information processing …

Uncertainty relations are the hallmarks of quantum physics and have been widely
investigated since its original formulation. To understand and quantitatively capture the …

Hyper-encoding enables storing several qubits in a single photon using its different degrees
of freedom like polarization and spatial ones. This approach enables feasible …

Identifying nonclassicality unambiguously and inexpensively is a long-standing open
challenge in physics. The no-signaling-in-time protocol was developed as an experimental …
