On the power of geometrically-local classical and quantum circuits
Kishor Bharti, Rahul Jain
We show a relation, based on parallel repetition of the Magic Square game, that can be solved, with probability exponentially close to (worst-case input), by (uniform) dep…
A quantum tug of war between randomness and symmetries on homogeneous spaces
Rahul Arvind, Kishor Bharti, Jun Yong Khoo +2
We explore the interplay between symmetry and randomness in quantum information. Adopting a geometric approach, we consider states as -equivalent if related by a symmetry transf…
Fault-tolerant hyperbolic Floquet quantum error correcting codes
Ali Fahimniya, Hossein Dehghani, Kishor Bharti +4
A central goal in quantum error correction is to reduce the overhead of fault-tolerant quantum computing by increasing noise thresholds and reducing the number of physical qubits r…
Certifying sets of quantum observables with any full-rank state
Zhen-Peng Xu, Debashis Saha, Kishor Bharti +1
We show that some sets of quantum observables are unique up to an isometry and have a contextuality witness that attains the same value for any initial state. We prove that these t…
Inferring physical laws by artificial intelligence based causal models
Jorawar Singh, Kishor Bharti, Arvind
The advances in Artificial Intelligence (AI) and Machine Learning (ML) have opened up many avenues for scientific research, and are adding new dimensions to the process of knowledg…
Fundamental Limitations on Communication over a Quantum Network
Junjing Xing, Tianfeng Feng, Zhaobing Fan +4
Entanglement, a fundamental feature of quantum mechanics, has long been recognized as a valuable resource in enabling secure communications and surpassing classical limits. However…
Pseudorandom unitaries are neither real nor sparse nor noise-robust
Tobias Haug, Kishor Bharti, Dax Enshan Koh
Pseudorandom quantum states (PRSs) and pseudorandom unitaries (PRUs) possess the dual nature of being efficiently constructible while appearing completely random to any efficient q…
