oach to cryptography and predicts new computers which could revolutionize
the types of calculations that are even possible. Much current effort is f
ocused on the intriguing possibility to control quantum systems to emulate
other quantum systems, to realize advanced quantum algorithms and to boo
tstrap quantum information for enhanced sensing. Evident challenges arise
when reasoning about quantum information systems: how might we understand\
, engineer and verify systems we can’t fully emulate using classical compu
ters? Moreover, today’s quantum processors can not execute the quantum al
gorithms and protocols you would find in books — i.e. Shor’s celebrated fa
ctoring algorithm which would break RSA cryptography appears out of reach\
, at least in its known form. A global research effort has discovered a ne
w means to operate quantum processors which requires feedback. This new me
thod merges ideas from machine learning to view a controllable quantum sys
tem as a machine learning model. This approach is not yet fully understood
. In this talk, I will explain some recent progress to understand this ne
w approach: our discovery of several limiting features of quantum approxim
ate optimization and the existence of avalanche effects in quantum circuit
training. I will also explain some more forward looking findings, includ
ing demonstrating the problem instance independence of optimized circuit p
arameters and my proof that the variational model is, in theory, a unive
rsal model of quantum computation.\n\n \n\nThroughout his career, Dr. Bia
monte's research has focused on practically-driven theoretical studies of
quantum information processing. He established the first experimentally re
levant universal models of adiabatic quantum computation and proved univer
sality of the variational model of quantum computation. He has published s
everal results in the development of quantum machine learning and the appl
ied mathematics of tensor networks. Several of his works consider the impa
ct of noise on quantum dynamics and quantum information processing and sen
sing with open quantum systems.\n\nUpon completing his undergraduate studi
es in electrical engineering, he worked as a quantum applications develop
er at D-Wave Systems Inc. in Vancouver, Canada and as a Fellow at Harvard
University in Cambridge Massachusetts in the Aspuru-Guzik group. Thereaft
er, he obtained a PhD from the University of Oxford in 2010. He then work
ed as part of a joint Oxford/Singapore postdoctoral program and as a Lectu
rer in Physics at St Peter's College Oxford before joining the Institute f
or Scientific Interchange (ISI Foundation) in Torino, Italy as the Quantu
m Science Research Group Leader (2012-2017). In 2017, Dr. Biamonte joined
the MIT founded Skolkovo Institute of Science and Technology as a Tenure
Track Associate Professor. He was subsequently promoted to Head of the Lab
oratory for Quantum Information Processing in 2019 and to tenured Professo
r in 2022. In April of 2022, Dr. Biamonte became the first American born
scientist to have successfully defended a higher Doctorate at the Moscow I
nstitute of Physics and Technology. Dr. Biamonte's time in Moscow was cut
abruptly short due to the war.\n\nDr. Biamonte's current research vision i
s to develop a data-driven approach to quantify emergent and collective ef
fects in quantum information processing tasks such as computing and sensin
g. Dr. Biamonte and his collaborators have recently discovered or been the
first to analytically predict several features of variational quantum alg
orithms including abrupt training transitions, reachability deficits and
parameter saturations. A passionate educator, Dr. Biamonte teaches applie
d and engineering mathematics, quantum information theory and quantum com
putation at the undergraduate and graduate level.
