We investigate cat codes that can correct multiple excitation losses and identify two types of
logical errors: bit-flip errors due to excessive excitation loss and dephasing errors due to …

While the on-chip processing power in circuit QED devices is growing rapidly, an open
challenge is to establish high-fidelity quantum links between qubits on different chips. Here …

Nonlocality, as established by the seminal Bell's theorem, is considered to be the most
striking feature of correlations present in spacelike separated events. Its practical application …

Quantum nonlocality, pioneered in Bell's seminal work and subsequently verified through a
series of experiments, has drawn substantial attention due to its practical applications in …

Quantum correlations and nonprojective measurements underlie a plethora of information-
theoretic tasks, otherwise impossible in the classical world. Existing schemes to certify such …

The paradigm of extracting work from an isolated quantum system through a cyclic
Hamiltonian process is a topic of immense research interest. The optimal work extracted …

We analyze the communication utility of a single quantum system when the sender and
receiver share neither any entanglement nor any classical shared randomness. To this aim …

Entanglement is of paramount importance in quantum information theory. Its supremacy over
classical correlations has been demonstrated in a numerous information theoretic protocols …

Sharing correlated random variables is a resource for a number of information theoretic
tasks such as privacy amplification, simultaneous message passing, secret sharing and …

Apart from the Bell nonlocality, which deals with the correlations generated from the local
input-output statistics, quantum theory exhibits another kind of nonlocality that involves the …
