Photonic Quantum Gates
In classical computing, we use logic gates (like AND, OR, NOT) to perform operations on bits. Each gate manipulates bits—values of 0 or 1—based on defined rules. In quantum computing,….

Cavity Quantum Electrodynamics (QED)
Before diving into cavity QED, let’s understand what quantum electrodynamics (QED) is. At its core, QED is the quantum theory of light and matter. It describes how photons (particles of….
Quantum Optomechanics
Optomechanics is the study of how light (optics) and mechanical systems (mechanics) interact. More specifically, quantum optomechanics looks at how quantum light interacts with tiny mechanical oscillators, such as membranes,….
Quantum Interference
Quantum interference is one of the most fascinating and essential features of quantum mechanics. It refers to the phenomenon where quantum particles like photons, electrons, or atoms interfere with themselves….
Entanglement Measures
Entanglement is one of the most fascinating and non-intuitive features of quantum mechanics. It refers to a situation where two or more quantum systems become so deeply connected that the….
Quantum Mutual Information
Let’s begin with the basic idea of mutual information from classical information theory. It tells us how much knowing one variable tells us about another. For example, if you know….
Quantum PCP Theorem
Before we can understand the Quantum PCP Theorem, we need to review the classical PCP (Probabilistically Checkable Proofs) Theorem. The PCP Theorem (a cornerstone of theoretical computer science) says: Any….
Cluster State Computing
Cluster State Computing is a radically different model of quantum computation compared to the more widely known gate-based model. Instead of using quantum gates applied step-by-step to qubits, it performs….
Digital twins in the cloud
Digital Twins in the Cloud: A Detailed Overview Digital twins are revolutionizing industries by providing virtual replicas of physical assets, systems, or processes. These digital models allow for real-time monitoring,….
Cloud robotics
Cloud Robotics: A Detailed Overview Cloud robotics is a groundbreaking field that brings together the power of cloud computing with robotic systems, enabling more advanced capabilities and applications for robots….
