Representing Measurement as a Thermodynamic Symmetry Breaking
- EconomicsSymmetry
- 2020
This work employs category-theoretic methods, particularly the theory of classifiers, to characterize the full interaction between observer and world in terms of information and resource flows and shows that breaking these symmetries induces decoherence, contextuality, and measurement-associated disturbance of the system of interest.
Sequential measurements, TQFTs, and TQNNs
- Mathematics, Computer Science
- 2022
Novel methods for implementing generic quantum information within a scale-free architecture and potential implementations of this framework in solid state physics are reviewed and applications to quantum simulation and biological information processing are suggested.
Sharing Nonfungible Information Requires Shared Nonfungible Information
- PhysicsQuantum Reports
- 2019
We show that sharing a quantum reference frame requires sharing measurement operators that identify the reference frame in addition to operators that measure its state. Observers restricted to finite…
Timelessness Strictly inside the Quantum Realm
- PhysicsEntropy
- 2021
It is proposed that a label of timelessness offers clues for rendering a Copenhagen-type interpretation of quantum physics more “realistic” and acceptable by providing a coarse but viable link from the fundamental quantum realm to the classical world which humans directly experience.
Generalized Holographic Principle, Gauge Invariance and the Emergence of Gravity à la Wilczek
- MathematicsFrontiers in Astronomy and Space Sciences
- 2021
We show that a generalized version of the holographic principle can be derived from the Hamiltonian description of information flow within a quantum system that maintains a separable state. We then…
Holographic Screens Are Classical Information Channels
- PhysicsQuantum Reports
- 2020
The ideas of classical communication and holographic encoding arise in different parts of physics. Here, we show that they are equivalent. This allows for us to reformulate the holographic principle…

Decoherence
- Physics, Computer SciencePrinciples of Quantum Computation and Information
- 2018
It is investigated here how the standard cryptographic assumption of shielded laboratory, stating that data generated by a secure quantum device remain private unless explicitly published, is disturbed by the einselection mechanism of quantum Darwinism explaining the measurement process by interaction with the external environment.
Quantum Darwinism: Entanglement, branches, and the emergent classicality of redundantly stored quantum information
- Computer Science
- 2006
The results show that the presence of redundancy divides information about the system into three parts: classical ( redundant); purely quantum; and the borderline, undifferentiated or "nonredundant," information.
Reconstruction of non-classical cavity field states with snapshots of their decoherence
- PhysicsNature
- 2008
The complete reconstruction and pictorial representation of a variety of radiation states trapped in a cavity in which several photons survive long enough to be repeatedly measured is reported.

The roles of decoherence and environment–induced superselection in the emergence of the classical from the quantum substrate are described. The stability of correlations between the einselected…
A model-theoretic interpretation of environment-induced superselection
- PhysicsInt. J. Gen. Syst.
- 2012
Einselection is reformulated in terms of positive operator-valued measures acting on a global quantum state and it is shown that this reformulation enables a natural interpretation of apparently classical systems as virtual machines that requires no assumptions beyond those of classical computer science.

Observers restricted to the observation of pointer states of apparatus cannot conclusively demonstrate that the pointer of an apparatus $\mathcal{A}$ registers the state of a system of interest S…
Decoherence of quantum superpositions through coupling to engineered reservoirs
- PhysicsNature
- 2000
Decoherence is induced by coupling the atom to engineered reservoirs, in which the coupling and state of the environment are controllable, and the decoherence rate scales with the square of a quantity describing the amplitude of the superposition state.
