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…
Oracle separations of hybrid quantum-classical circuits
Atul Singh Arora, Alexandru Gheorghiu, Uttam Singh
An important theoretical problem in the study of quantum computation, that is also practically relevant in the context of near-term quantum devices, is to understand the computatio…
All fundamental non-contextuality inequalities are unique
Kishor Bharti, Atul Singh Arora, Leong Chuan Kwek +1
Contextuality is one way of capturing the non-classicality of quantum theory. The contextual nature of a theory is often witnessed via the violation of non-contextuality inequaliti…
Quantum Weak Coin Flipping
Atul Singh Arora, Jérémie Roland, Stephan Weis
We investigate weak coin flipping, a fundamental cryptographic primitive where two distrustful parties need to remotely establish a shared random bit. A cheating player can try to…
