Metamaterials are artificial materials consisting of micro or nano composites which exhibit properties different from their components in sub-wavelength regime. These materials are finding applications in several areas such as…
Quantum Hamiltonian simulation (QHS) is one of the fundamental quantum sub-routines in quantum physics and quantum computing. QHS prepares a unitary approximately within some error bound for a given Hamiltonian.…
In this work, drawing inspiration from the type of noise present in real hardware, we study the output distribution of random quantum circuits under practical non-unital noise sources with constant…
Optical photons are excellent quantum information carriers, but weak optical nonlinearity poses significant challenges to these systems' scalability and computational capabilities. Currently, only probabilistic methods can achieve nonlinear quantum operations…
Introduced in 2010 by Scott Aaronson and Alex Arkhipov, Boson sampling is a specific quantum task demonstrating that a quantum device, even in the presence of noise, can outperform classical…
We explore the interplay between symmetry and randomness in quantum information. Adopting a geometric approach, we consider states as H-equivalent if related by a symmetry transformation characterized by the group…
A future quantum network will allow distributing entanglement over in principle arbitrarily long distances. This topic holds importance for applications in quantum information science as well as for fundamental investigations…
Entanglement detection and quantification of entanglement are the two most important problems in quantum information theory because quantum entanglement is a key resource in quantum information processing. I will divide…
Thanks to the rapid progress and growing complexity of quantum algorithms, correctness of quantum programs has become a major concern. Pioneering research over the past years has proposed various approaches…
Classical Bayes' rule lays the foundation for the classical causal relation between cause (input) and effect (output). This causal relation is believed to be universally true for all physical processes.…
