Quantum Thermometer can measure temperatures inside a quantum computer to living cell

The world, say many experts, is on the verge of a second quantum revolution. The most talked-about of such technologies is the quantum computer, a device in theory so powerful that it could crack the codes underlying internet security in just a few minutes. But full-scale quantum computers are still …

Graphene Bolometers emerging as high speed and sensitive Quantum photon detectors for quantum computation and quantum communication

Measurement connects the world of quantum phenomena to the world of classical events. It has both a passive role—in observing quantum systems—and an active one, in preparing quantum states and controlling them. In quantum physics, a measurement is the testing or manipulation of a physical system in order to yield …

Acoustic Metamaterials breakthroughs enable acoustic clocking, super-lensing , sound focusing and confinements

Metamaterials are artificially structured materials designed to control and manipulate physical phenomena such as light and other electromagnetic waves, sound waves and seismic waves in unconventional ways, resulting in exotic behavior that’s not found in nature. They are predicted to be able to protect the building from earthquakes by bending …

Nanolasers emerging technology for  optical interconnects, near-field spectroscopy and sensing, optical probing for biological systems, microprocessors and quantum circuits

Lasers are widely used in household appliances, medicine, industry, telecommunications and more.  A nanolaser is a laser that has nanoscale dimensions. These tiny lasers can be modulated quickly and, combined with their small footprint, this makes them ideal candidates for on-chip optical computing.   Several years ago, scientists introduced nanolasers …

Graphene enables room temperature single photon emitter and detector for unhackable Quantum Key Cryptography (QKD)

Quantum Key Distribution, or QKD, enables two remote parties, “Alice” and “Bob”, who are connected by a passive optical link to securely generate secret key material. Single-photon sources (SPSs) and single-photon detectors (SPDs) are key devices for enabling practical quantum key distributions (QKDs).  Single photon generation is necessary for secure quantum transmission; …

DARPA DeMi developing technologies for space based telescope on it’s military CubeSat satellite for Space Surveillance Awareness

The volume of space between the Earth’s surface out to geosynchronous orbit is enormous—equivalent to 240,000 times all the Earth’s oceans. Yet the number of objects calling that volume home is growing all the time—not just with satellites but with debris of all kinds, natural and manmade. And keeping track …

Chinese Scientists developing meta materials based Radar cloaks to enhance stealth of their warships, drones and fighter planes from radars

Stealth technology has proven to be one of the effective approaches to enhance the survivability of Aircrafts. Aircraft/helicopter designers are making them stealthier by reducing their signatures; viz. visual, aural, infrared (IR), and RADAR cross section. Advancements in stealth technologies, as demonstrated by the very low RCS of stealth aircraft …
