Molecular Qubits
Molecular qubits are a promising avenue for scalable and chemically tunable quantum computing. These qubits use molecules—synthetic or natural—as quantum information carriers, offering advantages in stability, design flexibility, and the….
Quantum Skyrmions
Quantum skyrmions are emerging as one of the most fascinating quasiparticles in condensed matter physics, with promising implications for quantum computing, spintronics, and data storage. Rooted in both particle physics….
Quantum Hardware Calibration
Quantum computing relies on extremely sensitive hardware that operates at the quantum level—where even the slightest imperfection or environmental interference can lead to errors. Quantum hardware calibration is the process….
Quantum Coherence and Thermodynamics
1. Introduction: The Intersection of Quantum and Thermodynamics Thermodynamics is a well-established field that deals with energy, heat, and work in macroscopic systems. On the other hand, quantum mechanics governs….
Quantum Work and Heat Definitions
1. Classical Foundations: Work and Heat Before diving into the quantum world, let’s revisit what work and heat mean in classical thermodynamics. In classical systems, work and heat are path-dependent….
Quantum Heat Engines
Let’s start with classical physics. A heat engine is a system that extracts useful work from heat energy flowing between two sources at different temperatures. The steam engine is a….
Optimal Control in Quantum Systems
Optimal control is a field of study that focuses on finding the best way to manipulate a system over time. In quantum mechanics, it deals with designing precise control strategies—typically….
Quantum Coherence in Optics
To understand quantum coherence, we need to first explore classical coherence. Coherence is a term that describes how predictably waves behave over time and space. If two light waves are….
Quantum Simulation of Biological Systems
Biology and quantum mechanics might seem like two completely different worlds — one deals with living organisms, the other with subatomic particles. But surprisingly, some of the most fundamental biological….
