SUMMARY:EFFICIENT CONTROL OF OPEN QUANTUM SYSTEM
DESCRIPTION:Featuring RENZO TAMIRO VILLAZON SCHOLER\, Boston University\, P
	hysics Department\n\nPart of the PhD Final Oral Exams.\n\nA major challenge
	 in the field of condensed matter physics is to harness the quantum mechani
	cal properties of microscopic systems coupled to large environments. Therma
	l fluctuations destroy quantum information and pose a difficult problem for
	 the development of quantum technologies such as quantum computers and memo
	ry devices. Recent advances in quantum control enable the manipulation of c
	omplex quantum states\, providing new paths to preserve quantum information
	 and to employ the environment as a resource. In this dissertation\, we dev
	elop practical quantum control protocols which quickly and efficiently tran
	sfer energy to/from an environment. A major contribution of this work is th
	e design of powerful and efficient quantum engines and refrigerators\, whic
	h use the environment either to generate useful work or to freeze a system 
	to it’s ground state. Such microscopic thermal machines yield an advantag
	e over their macroscopic counterparts since they harness atomic physics to 
	achieve enhanced efficiency and power. In achieving its core objectives\, t
	his work has also expanded on several areas of condensed matter quantum phy
	sics\, including (i) the theoretical characterization of special classes of
	 entangled system-environment states\, (ii) the discovery of novel quantum 
	chaotic phases of matter\, (iii) the design of control schemes which speed-
	up efficient adiabatic (slow) protocols\, and (iv) the development of exper
	imentally viable theoretical control schemes. This work paves the way for e
	xperimental implementations of efficient quantum control schemes in trapped
	 ion systems\, semiconductors\, and nano-diamonds.\n\n----\n\nJoin Zoom Mee
