Researchers have been trying to cool macroscopic mechanical oscillators down to their ground state for several decades. Nonetheless, past studies have merely attained the cooling of a few selected vibrational modes of such ...
Quantum secure direct communication (QSDC) is an important branch of quantum communication, based on the principles of quantum mechanics for the direct transmission of classified information. While recent proof-of-principle ...
In a recent issue of Physical Review A, Argonne researchers reported a new method for alleviating the effects of "noise" in quantum information systems, a challenge scientists around the globe are working to meet in the race ...
