PIRSA:19040099  ( MP4 Medium Res , MP3 , PDF ) Which Format?
Firewalls vs. Scrambling
Speaker(s): Beni Yoshida
Abstract: Recently we pointed out that the black hole interior operators can be reconstructed by using the Hayden-Preskill recovery protocols. Building on this observation, we propose a resolution of the firewall problem by presenting a state-independent reconstruction of interior operators. Our construction ... read more

Firewall vs. Scrambling (Part 1)
Speaker(s): Beni Yoshida
Abstract: Recently I pointed out that reconstruction of interior operators can be interpreted as the Hayden-Preskill recovery. Building on this observation, I will propose a resolution of the firewall puzzle by describing a state-independent reconstruction of interior operators which does not lead to the non-... read more

PIRSA:17040026  ( MP4 Medium Res , MP3 , PDF ) Which Format?
Decoding a black hole
Speaker(s): Beni Yoshida
Abstract: It is commonly believed that quantum information is not lost in a black hole. Instead, it is encoded into non-local degrees of freedom in some clever way; like a quantum error-correcting code. In this talk, I will discuss how one may resolve some paradoxes in quantum gravity by using the theory of q... read more

Instead, it is encoded into non-local degrees of freedom in some clever way; like a quantum error-correcting code.

Order parameter for chaos
Speaker(s): Beni Yoshida
Abstract: The fact that a black hole is a fast-scrambler is at the heart of black hole information paradoxes. It has been suggested that chaos can be diagnosed by using an out-of-time correlation function, which is closely related to the commutator of operators separated in time. In this talk I propose that t... read more

Fault-tolerant logical gates in quantum error-correcting codes
Speaker(s): Beni Yoshida
Abstract: Recently, Bravyi and Koenig have shown that there is a tradeoff between fault-tolerantly implementable logical gates and geometric locality of stabilizer codes. They consider locality-preserving operations which are implemented by a constant depth geometrically local circuit and are thus fault-toler... read more

Exotic topological order from quantum fractal code
Speaker(s): Beni Yoshida
Abstract: We present a family of three-dimensional local quantum codes with pairs of fractal logical operators. It has two polynomials over finite fields as input parameters which generate fractal shapes of anti-commuting logical operators, and possesses exotic topological order with quantum glas... read more

Quantum code with translation and scale symmetries
Speaker(s): Beni Yoshida
Abstract: Topological phases in spin systems are exciting frontiers of research with intimate connections to quantum coding theory. However, there is a disconnection between quantum codes and the idea of topology, in the absence of geometry and physical realizability. Here, we introduce a toy model, in which ... read more
