Quantum Cellular Automata, Tensor Networks, and Area Laws
Speaker(s): Ignacio Cirac
Abstract: Quantum Cellular Automata are unitary maps that preserve locality and respect causality. I will show that in one spatial dimension they correspond to matrix product unitary operators, and that one can classify them in the presence of symmetries, giving rise to phenomenon analogous to symmetry protec... read more

Bulk-boundary correspondence in PEPS
Speaker(s): Ignacio Cirac
Abstract: TBA

PIRSA:11040113  ( MP4 Medium Res , MP3 , PDF ) Which Format?
Entanglement spectrum and boundary theories with projected entangled-pair states
Speaker(s): Ignacio Cirac
Abstract: In many physical scenarios, close relations between the bulk properties of quantum systems and theories associated to their boundaries have been observed. In this work, we provide an exact duality mapping between the bulk of a quantum spin system and its boundary using Projected Entangled Pair State... read more

PIRSA:10050093  ( MP4 Medium Res , MP3 , PDF ) Which Format?
Description of many-body systems using MPS, PEPS, and other families of states
Speaker(s): Ignacio Cirac
Abstract: Matrix Product States (MPS) and their higher dimensional extensions, the Projected Entangled-Pair States (PEPS) can efficiently describe the ground and thermal states of interacting systems with short-range interactions. We will describe some mathematical properties of this families of states, as we... read more

Harnessing Quantum Physics
Abstract: This panel will explore some of the deepest questions facing those who would harness the power of quantum mechanics in new quantum technologies: What are the newest and most interesting discoveries researchers have made about quantum information? What progress has been made in recent years towards e... read more
