Pseudorandom quantum authentication
Tobias Haug, Nikhil Bansal, Wai-Keong Mok +2
We introduce the pseudorandom quantum authentication scheme (PQAS), an efficient method for encrypting quantum states that relies solely on the existence of pseudorandom unitaries…
Local contextuality-based self-tests are sufficient for randomness expansion secure against quantum adversaries
Jaskaran Singh, Cameron Foreman, Kishor Bharti +1
In quantum cryptography, secure randomness expansion involves using a short private string of random bits to generate a longer one, even in the presence of an adversary who may hav…
Self-Testing of a Single Quantum System: Theory and Experiment
Xiao-Min Hu, Yi Xie, Atul Singh Arora +13
Certifying individual quantum devices with minimal assumptions is crucial for the development of quantum technologies. Here, we investigate how to leverage single-system contextual…
NISQ Algorithm for Hamiltonian Simulation via Truncated Taylor Series
Jonathan Wei Zhong Lau, Tobias Haug, Leong Chuan Kwek +1
Simulating the dynamics of many-body quantum systems is believed to be one of the first fields that quantum computers can show a quantum advantage over classical computers. Noisy i…
Noisy intermediate scale quantum simulation of time dependent Hamiltonians
Jonathan Wei Zhong Lau, Kishor Bharti, Tobias Haug +1
Quantum computers are expected to help us to achieve accurate simulation of the dynamics of many-body quantum systems. However, the limitations of current NISQ devices prevents us…
Quantum Assisted Eigensolver
Kishor Bharti
We propose a hybrid quantum-classical algorithm for approximating the ground state and ground state energy of a Hamiltonian. Once the Ansatz has been decided, the quantum part of t…
