However, the quantum states they rely on are prone to decohering – that is, losing their quantum information due to local noise. One possible way around this is to use quantum bits (qubits) ...

An international group of researchers have investigated the role of memory in quantum systems and dynamics. Their findings show that a quantum process can appear memoryless from one perspective while ...

Quantum computing technology is complex, getting off the ground and maturing. There is promise of things to come. potentially ...

Preserving quantum information is key to developing useful quantum computing systems. But interacting quantum systems are chaotic and follow laws of thermodynamics, eventually leading to information ...

Quantum computing may sound like science fiction, but it’s here today, and it represents the shiny new thing in high performance computing. Where classical computers make use of binary bytes to store ...

Physicists have coaxed clusters of thousands of atoms into a delicate quantum limbo, creating a record breaking version of Schrödinger’s famous cat that is both “here” and “there” at once. By pushing ...

Physicists have put thousands of atoms into a "Schrödinger's cat" state — smashing the record for the most macroscopic object to be observed in a quantum state. In a new study, researchers observed ...

Light does not “think” in any human sense. Still, under the right conditions, it can behave in a way that looks uncannily like a memory system.
