Quantum communication is a secure way to transfer quantum information and to
communicate with legitimate parties over distant places in a network. Although …

In this paper, we propose quantum circuits for runtime assertions, which can be used for
both software debugging and error detection. Runtime assertion is challenging in quantum …

Controlled quantum teleportation involves a third party as a controller for the teleportation of
state. Here, we present the novel protocols for controlling teleportation of the arbitrary two …

Quantum cheques could be a forgery-free way to make transaction in a quantum networked
banking system with perfect security against any no-signalling adversary. Here, we …

One of the most fascinating aspects of quantum networks is their capability to distribute
entanglement as a nonlocal communication resource. In a first step, this requires network …

Construction of a fault-tolerant quantum computer remains a challenging problem due to
unavoidable noise and fragile quantum states. However, this goal can be achieved by …

The 5-qubit quantum computer prototypes that IBM has given open access to on the cloud
allow the implementation of real experiments on a quantum processor. We present the …

We propose a scheme for realizing parity measurement of cat-state qubits based on a
topological quantum phase transition. The cat-state qubits, formed by the bosonic modes in …

Local implementation of non-local quantum gates is necessary in a distributed quantum
computer. Here, we demonstrate the non-local implementation of controlled-unitary quantum …

This paper demonstrates the use of entanglement resources in quantum speedup by
presenting an algorithm which is the generalization of an algorithm proposed by Goswami …
