Quantum multi-programming is a method utilizing contemporary noisy intermediate-scale quantum computers by executing multiple quantum circuits concurrently. Despite early research…
Quantum search on noisy intermediate-scale quantum devices
Kun Zhang, Kwangmin Yu, Vladimir Korepin
Quantum search algorithm (also known as Grover's algorithm) lays the foundation for many other quantum algorithms. Although it is very simple, its implementation is limited on nois…
Maximal entanglement increase with single-photon subtraction
Kun Zhang, Jietai Jing, Nicolas Treps +1
Entanglement is an indispensable quantum resource for quantum information technology. In continuous-variable quantum optics, photon subtraction can increase the entanglement betwee…
Implementation of efficient quantum search algorithms on NISQ computers
Kun Zhang, Pooja Rao, Kwangmin Yu +2
Despite the advent of Grover's algorithm for the unstructured search, its successful implementation on near-term quantum devices is still limited. We apply three strategies to redu…
Depth optimization of quantum search algorithms beyond Grover's algorithm
Kun Zhang, Vladimir E. Korepin
Grover's quantum search algorithm provides a quadratic speedup over the classical one. The computational complexity is based on the number of queries to the oracle. However, depth…
Quantum partial search for uneven distribution of multiple target items
Kun Zhang, Vladimir Korepin
Quantum partial search algorithm is approximate search. It aims to find a target block (which has the target items). It runs a little faster than full Grover search. In this paper,…
