Beam Me Up Scotty: Physicists Calculate Energy Needed For Teleportation
2013-07-30 13:53:26

Lee Rannals for redOrbit.com - Your Universe Online Physics students have determined what energy it would take in order for the fictional Star Trek character Scotty to beam up Captain Kirk. Four University of Leicester physics students published a paper in the School's Journal of Physics Special Topics explaining that the energy required to teleport one person is shown to be dependent on bandwidth, meaning a decrease in time creates an increase in power consumption. In order for a...

Detection Of Single Photons Through Quantum Entanglement
2013-07-08 10:47:20

University of Innsbruck Almost 200 years ago, Bavarian physicist Joseph von Fraunhofer discovered dark lines in the sun's spectrum. It was later discovered that these spectral lines can be used to infer the chemical composition and temperature of the sun's atmosphere. Today we are able to gain information about diverse objects through light measurements in a similar way. Because often very little light needs to be detected for this, physicists are looking for ever more sensitive...

New Method To Distinguish Between Neighboring Quantum Bits
2013-06-18 09:01:59

University of New South Wales Researchers at the University of New South Wales have proposed a new way to distinguish between quantum bits that are placed only a few nanometers apart in a silicon chip, taking them a step closer to the construction of a large-scale quantum computer. Quantum bits, or qubits, are the basic building blocks of quantum computers - ultra-powerful devices that will offer enormous advantages for solving complex problems. Professor Michelle Simmons, leader of...

New Quantum Technologies Enabled With Spintronics Approach
2013-06-04 16:20:51

University of Chicago A team of researchers, including members of the University of Chicago´s Institute for Molecular Engineering, highlight the power of emerging quantum technologies in two recent papers published in the Proceedings of the National Academy of Sciences. These technologies exploit quantum mechanics, the physics that dominates the atomic world, to perform disparate tasks such as nanoscale temperature measurement and processing quantum information with lasers. The two...

JQI lab sets a new record for creating heralded photons HERALDING Entanglement, by general consensus of physicists, is the weirdest part of quantum science. To say that two particles, A and B, are entangled means that they are actually two parts of an inseparable quantum thing. An important consequence of this inherent kinship is that measuring a property of A (say, the particle's polarization) is necessarily to know the corresponding property of B, even if you're not there with a...
