Beyond QKD Nodes APRIL 14, 2024 | Rajesh Kumar Krishnan & Sidhartha Pant SHARE Quantum Key Distribution (QKD) is a ground-breaking method of secure communication that harnesses the principles of quantum mechanics. It enables two parties to generate a shared random secret key, known only to them, which can be used to encrypt and decrypt messages. The primary goal of a quantum key distribution network is to provide secret keys to any users or applications that require a high level of security. Broadening the Horizons of Point-to-Point Quantum Key Distribution Systems Tradit ..read more

Back to blogs Quantum 101: Unveiling Quantum Tunnelling QNu Labs   |   Feb 02, 2024 Quantum tunnelling is one of the most intriguing phenomena in quantum physics. Tunnelling may appear to have little relevance to everyday life but it is a fundamental process of nature that is responsible for many things on which life itself is dependent. It has even been hypothesised that the very beginning of the universe was caused by a tunnelling event, allowing the universe to pass from a “state of no geometry” (no space or time) to a state in which space, time, matter, and l ..read more

Back to blogs Quantum 101 - What is a Qubit? QNu Labs   |   Jan 30, 2024 Just as bits are the fundamental object of information in classical computing, qubits (quantum bits) are the fundamental object of information in quantum computing.  To comprehend the concept of a qubit, one must first grasp the essence of quantum computing. Unlike classical computers, which operate based on binary bits—units of information—quantum computers harness the peculiar phenomena of superposition and entanglement to process data in a fundamentally different manner. While a bit ..read more
