Quantum Algorithms to Determine Spin-Resolved Exchange-Correlation Potential for Strongly Correlated Materials
H. Arslan Hashim, Volodymyr M. Turkowski, Eduardo R. Mucciolo
Accurate exchange-correlation (XC) potentials are essential for density functional theory, yet reliable approximations remain challenging for strongly correlated systems. In this w…
Green's Function Methods for Computing Supercurrents in Josephson Junctions
Eduardo R. Mucciolo, Jouko Nieminen, Xiao Xiao +3
Interest in Josephson junctions (JJs) has increased rapidly in recent years not only because of their use in qubits and other quantum devices but also due to the unique physics sup…
Separation of Statistical Complexity and Trainability in Variational Quantum Circuits
Suman Mandal, Maximillian Daughtry, Eduardo R. Mucciolo
Variational quantum algorithms (VQAs) are among the leading approaches for near-term quantum computing, yet their performance can degrade in barren plateau regimes characterized by…
Circuit complexity and functionality: a thermodynamic perspective
Claudio Chamon, Andrei E. Ruckenstein, Eduardo R. Mucciolo +1
Circuit complexity, defined as the minimum circuit size required for implementing a particular Boolean computation, is a foundational concept in computer science. Determining circu…
A Matrix Product State Representation of Boolean Functions
Umut Eren Usturali, Claudio Chamon, Andrei E. Ruckenstein +1
We introduce a novel normal form representation of Boolean functions in terms of products of binary matrices, hereafter referred to as the Binary Matrix Product (BMP) representatio…
