The quantum entanglement of particles, such as photons, is a prerequisite for the new and future technologies of quantum computing, telecommunications, and cyber security. Real-world applications that take advantage of this technology, however, will not be fully realized until devices that produce such quantum states leave the realms of the laboratory and are made both small and energy efficient enough to be embedded in electronic equipment. In this vein, European scientists have created and installed a tiny "ring-resonator" on a microchip that is claimed to produce copious numbers of entangled photons while using very little power to do so.
John Martinis’ research group at the University of California at Santa Barbara has created the first quantum computer
with the quantum equivalent of conventional Von Neumann architecture. This general-purpose programmable quantum computer is realized using superconducting circuits and offers greater potential for large-scale quantum computing than the one-problem devices that have been demonstrated in this emerging field to date.
Scientists at Cornell University
report they can now use a light beam carrying a single milliwatt of power to move objects and even change the optical properties of silicon from opaque to transparent at the nanometric scale. Such an advancement could prove very useful for the future of micro-electromechanical (MEMS) and micro-optomechanical (MOMS) systems.
Researchers are developing a new class of tiny mechanical devices, made up of vibrating structures the thickness of a human hair, that could be used to filter electronic signals in cell phones and other applications. Only the size of a grain of sand, these microelectromechanical systems (MEMS) will, nonetheless, improve performance and reduce power usage.
