Blockchain with proof of quantum work doi.org/10.1103/m9jd-z9my

Blockchain with proof of quantum work

We propose a blockchain architecture in which mining requires a quantum computer. The consensus mechanism is based on proof of quantum work, a quantum-enhanced alternative to traditional proof of...

Tunable quantum Zeno effect in an artificial giant atom doi.org/10.1103/hsw5-nmjg

Tunable quantum Zeno effect in an artificial giant atom

The quantum Zeno effect, arising from frequent measurements or strong system-environment interactions, has typically been considered difficult to actively control in point-like atomic systems. Here,...

Spatiotemporal diffraction-free wave packets of the caustic waveforms doi.org/10.1103/1fbg-jlct

Spatiotemporal diffraction-free wave packets of the caustic waveforms

In this article we introduce a continuum of families of nondiffracting spatiotemporal optical wave packets that exhibit caustic waveforms in both space and time. We show that their envelopes admit...

From Qubit to Qubit: A Graduate Course in Quantum Mechanics arxiv.org/abs/2605.01585

From Qubit to Qubit: A Graduate Course in Quantum Mechanics

This textbook is drawn from notes for a two-semester graduate course in quantum mechanics. It begins with the most constrained quantum system, and recovers the rest of the subject by relaxing...

Maxwell's demon for quantum transport doi.org/10.1103/rhvv-yd6w

Maxwell's demon for quantum transport

While most of the existing quantum information engines assisted by Maxwell's demon harness thermal fluctuations, those that rectify only quantum fluctuations have recently been constructed. We...

Schroedinger's Equation at 100: The Wave Picture That Helped...

Schroedinger's equation gave early quantum theory a visual language that looked like physics again: a wave evolving by a linear differential equation. This essay argues that the same success also...

Ion stopping force from Bohmian mechanics doi.org/10.1103/7plq-xskx

Ion stopping force from Bohmian mechanics

We employed Bohmian mechanics to solve the equations of motion for a charged particle traveling in a free electron gas. Quantum effects are accounted for by including the Bohm quantum-mechanical...

Quantum mechanics over real numbers fully reproduces standard quantum theory arxiv.org/abs/2604.19482

Quantum mechanics over real numbers fully reproduces standard...

Standard quantum mechanics employs complex Hilbert spaces, but whether complex numbers are fundamental or merely convenient has long been debated. For decades, real-valued equivalents were...

Consciousness, Quantum Mechanics, and the Limits of Scientific Objectivism

Consciousness and quantum mechanics are among the most puzzling phenomena studied in the sciences. Some scholars suggest they are related, though others think this claim commits a "minimization of...

Chaos and Quantum Tunneling arxiv.org/abs/2604.12926

Chaos and Quantum Tunneling

In generic Hamiltonian systems that are neither completely integrable nor fully chaotic, phase space consists of a mixture of regular and chaotic components. In classical dynamics, transitions...

Can the present be the average of the future?

We introduce a two state vector formalism of quantum mechanics by generalizing Bell hidden variable model to higher dimensions and by attributing a physical significance, a state evolving backward...

Reshaping the Quantum Arrow of Time doi.org/10.1103/l18s-9vmh

Reshaping the Quantum Arrow of Time

A quantum control Hamiltonian is developed that can blur or even reverse the perceived arrow of time in monitored systems, enabling new ways to emulate backward-in-time dynamics and extract energy to...

Optimal min-entropy uncertainty relation

Entropic uncertainty relations have been a famed research topic for over 65 years with many applications and still many unknowns left. For example, even for single-qubit states, the optimal min-ent...

Quantum reflection time and the Goos-H\"anchen effect

We explore the analogy between following the motion of a reflected wave packet and a quantum measurement of the spatial delay imposed on the particle by the scattering potential. It is shown that...
