Quantum information systems leverage the principles of quantum mechanics to process and store information in ways that classical systems cannot. These systems utilize quantum bits, or qubits, which, unlike classical bits that represent either 0 or 1, can exist in superpositions of states. This ability allows quantum computers to perform complex computations simultaneously, vastly increasing their potential processing power. The potential applications of quantum information systems span various fields, including cryptography, optimization, and materials science.  Research at UMass Amherst focusses on  advanced topics in classical and quantum information systems and networks, and secure communications
