Design Rules for Quantum Imaging Devices: Experimental Progress Using CMOS Single Photon Detectors
White Papers The authors had earlier introduced a set of quantum-based design rules directed at quantum engineers who design single-photon quantum communications and quantum imaging devices. This paper reports on experimental progress using SPAD (Single Photon...

BodyTechnic: Cancer treatment spares healthy tissue
News The photon radiosurgery system (PRS) uses an NEC V25+ 16bit CISC microcontroller with an enhanced X86 instruction to control a beam of therapeutic radiation delivered to tumour sites. Compared to the linear accelerator, the photon radiosurgery...

Researchers cut costs of quantum cryptography
News One of the major costs in quantum cryptography is for photon measurement detectors, which can cost between $5,000 (£2,500) and $20,000 (£10,000), according to Nist. Researchers from the organisation claim they can halve, and even quarter, the...

Businesses told to build 'tech watch lists'
Blog Comment Trend watchers may wish to look at the explorations of the pico/femtoscale structures by mathematical modeling which potentiates or transcends AFM/SEM optical inspections with electron, wave, energy field, force field-matrix, thermic tint, and...

More boson goes on - computing with excitons...
Blog When an electron falls into a hole, it gives out energy as a photon - that's how LEDs work - but the prelapsarian state can be considered as a particle in its own right. You can convert a photon back into an exciton too, which is how solar cells...

Toshiba shows practical quantum cryptography
News These photons can be modulated in one of two ways through two different kinds of polarisation, but according to Heisenberg's Uncertainty Principle it is impossible to know both the kind of polarisation and the data represented by the photon.

No, no, no
Talkback If they absorb a photon they will rise to some higher allowed energy level (= a higher "orbit") but they will normally re-emit that energy as another photon later, and fall back to the lower energy level.

Intel claims quantum leap in fibre-optic detectors
News Photodetectors work by capturing a photon (a quantised particle of light) that comes in and is absorbed by a material, which then converts a photon into electrical energy (an electron). In Paniccia's avalanche photodetector, the electrical energy...

Intel: Chips will network the world
News You can't do half a photon," Gelsinger noted. Hypothetically, optical communications equipment, which transmits data via photons rather than electrons, may hit a finite shrinkage point because "a photon is only so small.

what is 'information'?
Talkback Surely if 'something' travels faster than light, even if it is just one single photon, then that can be used for information?
