SUMMARY:The phase diagram of quantum state preparation : limitations and co
	mplexity
DESCRIPTION:Featuring Alexandre Day\, Boston University\n\nPart of the Biop
	hysics/Condensed Matter Seminar Series.\n\nPreparing quantum states efficie
	ntly and with high fidelity is a key stepping stone towards building a reli
	able and scalable quantum computer.\nIn this talk I will present some of th
	e fundamental limitations of quantum state preparation. In particular I wil
	l discuss how having finite preparation time leads to different phases in t
	erms of the difficulty of obtaining optimal fidelity. We find strong eviden
	ce for the existence of a generic NP-hard phase analogous to a spin glass\,
	 where finding the optimal preparation protocol is exponentially hard. We s
	upport these findings using different machine learning approaches such as r
	einforcement learning and simulated annealing.
