As quantum computing continues to develop, it introduces a threat to modern-day security standards. Quantum computing can’t break our widely used encryption methods today, but it threatens them with the possibility of decryption of saved […]
Quantum 8, 1505 (2024). https://doi.org/10.22331/q-2024-10-23-1505 We propose a simple, robust protocol to prepare a low-energy state of an arbitrary Hamiltonian on a quantum computer or programmable quantum simulator. The protocol is inspired by the adiabatic […]
Quantum 8, 1504 (2024). https://doi.org/10.22331/q-2024-10-23-1504 We develop quantum algorithms for pricing Asian and barrier options under the Heston model, a popular stochastic volatility model, and estimate their costs, in terms of T-count, T-depth and number […]
Insider Brief Google Quantum AI’s new LUCI error correction framework improves fault tolerance in quantum computers by dynamically adapting circuits to handle defective qubits and couplers, achieving a 36× reduction in logical error rates compared […]
Insider Brief A new article in Nature warns that the rapid development of quantum technologies, especially in defense, demands robust ethical governance to prevent risks like privacy violations and cyberattacks. The researchers emphasize that ongoing […]
Insider Brief The Department of Defense and U.S. Small Business Administration announced the first group of investment funds approved under the Small Business Investment Company Critical Technology Initiative (SBICCT Initiative), planning to invest over $2.8 […]
Insider Brief TU Wien researchers, in collaboration with Chinese teams, have developed simulations to investigate ultrafast quantum processes, revealing how quantum entanglement arises on attosecond time scales. In their study, electrons hit by an intense […]
The emergence of quantum entanglement is one of the fastest processes in nature. Scientists show that using special tricks, this can be investigated on an attosecond scale. Scientists have managed to analyze ulrafast processes which […]
by Amara Graps – Which- quantum computing modality is best suited for -which- Use Case, beyond what we know for the gate-based versus annealing types? In an earlier QCR article about the Ansatz Zoo, I […]
Quantum theory describes events that take place on extremely short time scales. In the past, such events were regarded as ‘momentary’ or ‘instantaneous’: An electron orbits the nucleus of an atom—in the next moment it […]
