Atoms and molecules on the same wavelength
(Phys.org) —It may be surprising, but in physics the terrain of atoms and the territory of organic molecules are worlds apart. Therefore, in order to have a molecule communicate optically with atoms, the ...
New analysis eliminates a potential speed bump in quantum computing
A quantum particle can search for an item in an unsorted "database" by jumping from one item to another in superposition, and it does so faster than a classical computer ever could.
Another step toward quantum computers: Using photons for memory
(Phys.org) —Scientists at Yale University have found a new way to manipulate microwave signals that could aid the long-term effort to develop a quantum computer, a powerful tool that would revolutionize ...
Quantum physics secures new cryptography scheme
The way we secure digital transactions could soon change. An international team has demonstrated a form of quantum cryptography that can protect people doing business with others they may not know or trust ...
