Quantum Many-Body Physics in Quantum Computing

by Leonardo Banchi (Univ. Florence)


After many years of theoretical research, quantum computing is finally entering an era where quantum devices are actually being built. Although these
early devices lack either the size or fault-tolerance to run full-scale quantum algorithms, they are nonetheless made up of many quantum entities, or qubits. In
this talk I will show how techniques borrowed from quantum many-body physics, (integrable) field theory and random matrix theory, can be applied to better
understand and program the behaviour of these quantum devices. In particular, I will discuss applications in quantum cryptography, quantum communication and
machine learning.
