The Spacetime View of the Information Paradox
- Physics
- 2009
In semiclassical gravity, the final state of black-hole evaporation cannot be described by a pure state. Nevertheless, we point out that the system can be described by a generalized pure state, which…
Time in quantum gravity and black-hole information paradox
- Physics, Philosophy
- 2011
The fact that canonical quantum gravity does not possess a fundamental notion of time implies that the theory is unitary in a trivial sense. At the fundamental level, this trivial unitarity leaves no…
QFT AS PILOT-WAVE THEORY OF PARTICLE CREATION AND DESTRUCTION
- Physics
- 2010
States in quantum field theory (QFT) are represented by many-particle wave functions, such that a state describing n particles depends on n space–time positions. Since a general state is a…
Black hole information paradox without Hawking radiation
- Physics
- 2018
By entangling soft massless particles one can create an arbitrarily large amount of entanglement entropy that carries an arbitrarily small amount of energy. Dropping this entropy into the black hole…
If time is a local observable, then Hawking radiation is unitary
- Physics
- 2014
In the usual formulation of quantum theory, time is a global classical evolution parameter, not a local quantum observable. On the other hand, both canonical quantum gravity (which lacks fundamental…
Time Dependence of Hawking Radiation Entropy
- Physics
- 2013
If a black hole starts in a pure quantum state and evaporates completely by a unitary process, the von Neumann entropy of the Hawking radiation initially increases and then decreases back to zero…
Time dependence of Hawking radiation entropy

If a black hole starts in a pure quantum state and evaporates completely by a unitary process, the von Neumann entropy of the Hawking radiation initially increases and then decreases back to zero…
Correlations in Hawking radiation and the infall problem
- Physics
- 2011
It is sometimes believed that small quantum gravity effects can encode information as ‘delicate correlations’ in Hawking radiation, thus saving unitarity while maintaining a semi classical horizon. A…
Relativistic quantum information and time machines

Relativistic quantum information combines the informational approach to understanding and using quantum mechanical systems – quantum information – with the relativistic view of the Universe. In this…

What Exactly is the Information Paradox

The black hole information paradox tells us something important about the way quantum mechanics and gravity fit together. In these lectures I try to give a pedagogical review of the essential physics…
Conservative solutions to the black hole information problem

We propose a novel scheme to classify the different options for resolution of the black hole loss of information problem that is independent of the details of the underlying theory of quantum…
Black holes and massive remnants.
- PhysicsPhysical review. D, Particles and fields
- 1992
This paper examines the conundrum faced when one attempts to understand the dynamics of black hole formation and evaporation without abandoning unitary evolution: remnants that carry large amounts of information and whose size and mass depend on their information content.
Time in relativistic and nonrelativistic quantum mechanics
- Physics
- 2008
The kinematic time operator can be naturally defined in relativistic and nonrelativistic quantum mechanics (QM) by treating time on an equal footing with space. The spacetime-position operator acts…
Particle creation by black holes

AbstractIn the classical theory black holes can only absorb and not emit particles. However it is shown that quantum mechanical effects cause black holes to create and emit particles as if they were…
Spacetime information.

A four-dimensional notion of the information available about a quantum system's boundary conditions in the various sets of decohering histories it may display is introduced.
Physics in the real universe: time and spacetime

The Block Universe idea, representing spacetime as a fixed whole, suggests the flow of time is an illusion: the entire universe just is, with no special meaning attached to the present time. This…
Breakdown of Predictability in Gravitational Collapse

The principle of equivalence, which says that gravity couples to the energy-momentum tensor of matter, and the quantum-mechanical requirement that energy should be positive imply that gravity is…
