Interdisciplinary Quantum Research
Quantum science is no longer confined to the domain of theoretical physics. It has grown into a vibrant, cross-cutting field with profound implications across multiple disciplines. This evolution is largely….
Startups in Quantum Cryptography
Quantum cryptography is emerging as one of the most crucial subfields within quantum technology, offering unprecedented levels of communication security. As quantum computers threaten to break existing encryption methods, startups….
Single-Photon Sources
A single-photon source is a device or system that emits one and only one photon at a time, on demand or probabilistically. In quantum technologies, especially quantum communication and quantum….
No-Cloning Theorem
The No-Cloning Theorem is a fundamental principle of quantum mechanics that states: It is impossible to create an exact copy of an arbitrary unknown quantum state. In simple terms, you….
Quantum Information Disturbance Trade-off
In classical physics, if you want to know about a system—like measuring a car’s speed or temperature—you can simply observe it. The act of measuring doesn’t significantly affect the car….
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….
Holevo Bound
In classical communication, if you send a message—say a letter or a digital bit—the receiver gets the full message. If you send 1 bit, the receiver gets 1 bit of….
Quantum Entropy Measures
In classical information theory, entropy is used to measure uncertainty or the average information content of a message. This idea is extended in the quantum world through quantum entropy measures,….
Complexity of Quantum Sampling Problems
At a high level, quantum sampling problems ask: Can a quantum computer efficiently sample from a probability distribution that is hard (or impossible) for a classical computer to sample from?….
