Advancements in quantum computing, such as Google’s Willow chip, pose a threat to today’s means of encryption, University of Kent lecturer Carlos Perez-Delgado argued. For Bitcoin, protecting ...
It's time the crypto community faced up to the challenge of super-computing to their networks, says CoinDesk's chief content officer.
By Bruce Ng Ever since Bitcoin was created, the perennial question, asked by skeptics and advocates alike, could be condensed into four simple words: Can Bitcoin be hacked? The perennial answer ...
Post-quantum cryptography (PQC), sometimes referred to as quantum-proof, quantum-safe, or quantum-resistant, is the development of cryptographic algorithms (usually public-key algorithms) that are currently thought to be secure against a cryptanalytic attack by a quantum computer.
Neuromorphic quantum computing (abbreviated as ‘n.quantum computing’) is an unconventional type of computing that uses neuromorphic computing to perform quantum operations. It was suggested that quantum algorithms, which are algorithms that run on a realistic model of quantum computation, can be computed equally efficiently with ...
Quantum processors are difficult to compare due to the different architectures and approaches. Due to this, published physical qubit numbers do not reflect the performance levels of the processor. This is instead achieved through the number of logical qubits or benchmarking metrics such as quantum volume , randomized benchmarking or circuit ...
In the classical setting, i.e. without quantum communication, one player can (in principle) always cheat against any protocol. [4] There are classical protocols based on commitment schemes, but they assume that the players lack the computing power to break the scheme. In contrast, quantum coin flipping protocols can resist cheating even by ...
