Sending quantum information through a chain of qubits, like energy through a Newton's cradle, could be the key to faster operations and take quantum computing to the next level.
Quantum information is notoriously fragile. Internet traffic is anything but. Yet Northwestern University scientists have demonstrated they can peacefully coexist inside the same fiber-optic cable.
Quantum networks, systems consisting of multiple connected nodes or devices that can transmit quantum information to one another, have the potential to advance future communications. These networks typically leverage entanglement, ...
One of the deepest ambitions in modern physics is understanding how the fabric of space and time could emerge from fundamental quantum degrees of freedom to establish a quantum theory of gravity.
The inevitable leakage of energy and information from a quantum system into its surrounding environment is the enemy of quantum technology. Now, researchers have demonstrated that it can be exploited to generate entanglement—the ...
A truly useful quantum computer must be able to run any algorithm, with the same versatility an ordinary laptop offers. Physicists have now shown a new way to give a quantum computer exactly that flexibility, harnessing the ...
Quantum technologies, which leverage the principles of quantum mechanics, have been found to outperform their classical counterparts on specific tasks. Among other things, past studies have highlighted the potential of quantum ...
Imagine shining a flashlight across a dark room. You can predict exactly what the light will do: travel in a straight line from one point to another. That seems obvious because, in the world we see around us, light appears ...
Future quantum computing will require correlations between distant modules—a feature known as distributed entanglement. Traditionally, such entanglement has relied on active control and repeated measurements. Now, physicists ...
Recent improvements in our understanding of how the principles of thermodynamics apply in the quantum realm could give a boost to quantum technology, and a clearer picture of quantum thermodynamics could in turn enhance our ...
