Architectural mechanisms of a universal fault-tolerant quantum computer
Dolev Bluvstein, Alexandra A. Geim, Sophie H. Li +20
Quantum error correction (QEC) is believed to be essential for the realization of large-scale quantum computers. However, due to the complexity of operating on the encoded `logical…
Scalable and fault-tolerant preparation of encoded k-uniform states
Shayan Majidy, Dominik Hangleiter, Michael J. Gullans
-uniform states are valuable resources in quantum information, enabling tasks such as teleportation, error correction, and accelerated quantum simulations. The practical realiza…
Thermodynamic limitations on fault-tolerant quantum computing
Mykhailo Bilokur, Sarang Gopalakrishnan, Shayan Majidy
We investigate the thermodynamic limits on scaling fault-tolerant quantum computers due to heating from quantum error correction (QEC). Quantum computers require error correction,…
Noncommuting charges can remove non-stationary quantum many-body dynamics
Shayan Majidy
Studying noncommuting conserved quantities, or 'charges,' has revealed a conceptual puzzle: noncommuting charges hinder thermalization in some ways yet promote it in others. While…
Noncommuting conserved charges in quantum thermodynamics and beyond
Shayan Majidy, William F. Braasch, Aleksander Lasek +3
Thermodynamic systems typically conserve quantities ("charges") such as energy and particle number. The charges are often assumed implicitly to commute with each other. Yet quantum…
Critical phase and spin sharpening in SU(2)-symmetric monitored quantum circuits
Shayan Majidy, Utkarsh Agrawal, Sarang Gopalakrishnan +3
Monitored quantum circuits exhibit entanglement transitions at certain measurement rates. Such a transition separates phases characterized by how much information an observer can l…
Non-Abelian symmetry can increase entanglement entropy
Shayan Majidy, Aleksander Lasek, David A. Huse +1
The pillars of quantum theory include entanglement and operators' failure to commute. The Page curve quantifies the bipartite entanglement of a many-body system in a random pure st…
How to build Hamiltonians that transport noncommuting charges in quantum thermodynamics
Nicole Yunger Halpern, Shayan Majidy
Noncommuting conserved quantities have recently launched a subfield of quantum thermodynamics. In conventional thermodynamics, a system of interest and an environment exchange quan…
Detecting violations of macrorealism when the original Leggett-Garg inequalities are satisfied
Shayan Majidy, Jonathan J. Halliwell, Raymond Laflamme
Macroscopic realism (MR) is the notion that a time-evolving system possesses definite properties, irrespective of past or future measurements. Quantum mechanical theories can, howe…
Exploration of an augmented set of Leggett-Garg inequalities using a noninvasive continuous-in-time velocity measurement
Shayan-Shawn Majidy, Hemant Katiyar, Galit Anikeeva +2
Macroscopic realism (MR) is the view that a system may possess definite properties at any time independent of past or future measurements, and may be tested experimentally using th…
A unification of the coding theory and OAQEC perspective on hybrid codes
Shayan Majidy
There is an advantage in simultaneously transmitting both classical and quantum information over a quantum channel compared to sending independent transmissions. The successful imp…
