Hi all,
Tomorrow Gian will give group meeting. He asked me to mention that it's
intended for non-experts and will be very accessible. The title and
abstract are below.
Best,
Ian

Title: Quantum computing in a nutshell: more with less
Abstract: Quantum computing is moving out of research labs to contribute to
the establishment of quantum technologies. There are two distinct aspects
of this process: On one side, the extreme miniaturization of
microprocessors requires to take into account quantum effects and, on the
other side, the fast development of quantum hardware indicates practical
routes to achieve scalable quantum devices. Quantum technologies hold the
promise and the potential to revolutionize how we perform several tasks,
ranging from more powerful computation, to intrinsically secure
cryptography, to more precise metrology. In this talk, I will motivate the
quest to build a quantum computer and explain the way it works without
assuming any familiarity with quantum mechanics, but recalling only
concepts from linear algebra. In the second part, I will connect the
general picture to a few recent results: In the context of adiabatic
quantum computation, we developed a method to characterize the performance
of large quantum optimizers using exponentially less classical resources.
In the context of quantum linear networks, we proposed a strong candidate
for the first post-classical computation of practical relevance that
involves less resources than universal quantum computation.
