Novel protocol reconstructs quantum states in large-scale experiments up to 96 qubits
Quantum computers, systems that process information leveraging quantum mechanical effects, could outperform classical computers on some computationally demanding tasks. Despite their potential, as the size of quantum computers increases, reliably describing and measuring the states driving their functioning becomes increasingly difficult.Quantum Physics NewsRead More
A universal scheme can verify any quantum state
Quantum technologies, devices that can process, store, or detect information leveraging quantum mechanical effects, could outperform classical devices in some tasks or scenarios. Despite their potential, verifying that these devices work correctly and truly realize desired quantum states can be challenging, particularly when they cannot be fully examined or inspected.Quantum Physics NewsRead More
Quadratic gravity theory reshapes quantum view of Big Bang
Waterloo scientists have developed a new way to understand how the universe began, and it could change what we know about the Big Bang and the earliest moments of cosmic history. Their work suggests that the universe’s rapid early expansion could have arisen naturally from a deeper, more complete theory of quantum gravity. The paper,
