Time Travel Paradoxes and Entangled Timelines IJQF Weekly Papers • physics.hist-ph updates on arXiv.org / 2d arXiv:2303.07635v4 Announce Type: replace-cross Abstract: For time travel to be consistent with the known laws of physics, the resulting paradoxes must be resolved. It has been suggested that parallel timelines (a.k.a. multiple histories) may provide a resolution. However, so far, a concrete mechanism by which parallel… Read more →

Is the H Atom Surrounded by A Cloud of Virtual Quanta Due to the Lamb Shift? IJQF Weekly Papers • quant-ph updates on arXiv.org / 22h arXiv:2607.27257v1 Announce Type: new Abstract: \abstract{The Lamb shift, one of the most fundamental interactions in atomic physics, arises from the interaction of H atoms with the electromagnetic fluctuations of the quantum vacuum. The energy shift has… Read more →
An Operational Resolution of the Third-Particle Paradox IJQF Weekly Papers • quant-ph updates on arXiv.org / 23h arXiv:2607.20815v1 Announce Type: new Abstract: We give an operational resolution of the third-particle paradox, relevant in the theory of quantum reference frames. The apparent paradox is that a system which is irrelevant in one quantum-reference-frame description can seem to become relevant after changing to another… Read more →
Exact No Signaling in Time without Temporal Classicality IJQF Weekly Papers • quant-ph updates on arXiv.org / 22h arXiv:2607.14583v1 Announce Type: new Abstract: No signaling in time (NSIT) has often been treated as the clean operational remnant of noninvasive measurability. If an earlier measurement leaves every later marginal unchanged, the temporal process appears classical. We show that this inference is false. We… Read more →
The Geometry of Quantum Complexity in Open Systems IJQF Weekly Papers • quant-ph updates on arXiv.org / 20h arXiv:2607.08411v1 Announce Type: new Abstract: We extend Nielsen’s geometric approach for quantum complexity from closed to open quantum systems, whose dynamics is governed by Lindbladian evolution. In this framework, complexity is defined through an optimal-control problem on the space of mixed states, with a… Read more →

Mach’s principle in atomic transitions IJQF Weekly Papers • quant-ph updates on arXiv.org / 5h arXiv:2606.11608v1 Announce Type: new Abstract: We investigate the atomic transition probabilities in atom-mirror set-ups that are in circular motion. In one scenario, the atom is in circular motion inside a static cylindrical mirror. In the other scenario, the cylindrical mirror rotates around its central axis while the… Read more →
Protecting Quantum States via the Super-Zeno Effect and Anticoherence IJQF Weekly Papers • quant-ph updates on arXiv.org / 22h arXiv:2606.04681v1 Announce Type: new Abstract: We consider a spin system coupled to a noisy environment via an interaction Hamiltonian $H$ which is a polynomial of degree $n$ in the spin operators $S_i$ ($n$-magnetic Hamiltonian), and show that the use of the quantum super-Zeno… Read more →
Uncertainty relations in classical and quantum theories of electromagnetism IJQF Weekly Papers • quant-ph updates on arXiv.org / 19min arXiv:2605.28906v1 Announce Type: new Abstract: Sharp uncertainty relations restricting the values of variances in the position space and in the momentum (wavevector) space are derived. They have the same form $\Delta r\Delta k\ge 5/2$ in the classical theory of light beams, in the… Read more →
Collapse of the state vector and nonlocal correlations in quantum mechanics IJQF Weekly Papers • quant-ph updates on arXiv.org / 23h arXiv:2605.21243v1 Announce Type: new Abstract: It is shown how to obtain state vectors associated with measurements on the separated subystems of an entangled state, revealing how a single wavefunction encodes a set of statistical measurement outcomes. The result explains why measurements… Read more →
