Researchers create the first quantum
computer on a silicon chip.
Not exact matches
Unlike traditional
computers, in which a
silicon chip's transistors are either turned
on or off, a qubit can be both at the same time.
Quantum computing relies
on particles called quantum bits, or qubits, to process data, unlike modern
computers that rely
on transistors packed into conventional
silicon chips.
Whereas
silicon chips encode data in either two states —
on or off as represented by a «0» or «1» — qubits can store data in both states at the same time, potentially letting the
computers crunch data more quickly.
To suggest otherwise is silly, akin to saying that
silicon chips don't work (despite writing the comment
on a
computer using them.)
The tiny power
chips will be made
on six - inch
silicon carbide wafers using the same manufacturing technique used to make other types of
computer chips.
Instead of light,
computers run
on electrons moving through
silicon - based
chips — which, despite huge advances, are still less efficient than photonics.
These techniques include: human tissue created by reprogramming cells from people with the relevant disease (dubbed «patient in a dish»); «body
on a
chip» devices, where human tissue samples
on a
silicon chip are linked by a circulating blood substitute; many
computer modelling approaches, such as virtual organs, virtual patients and virtual clinical trials; and microdosing studies, where tiny doses of drugs given to volunteers allow scientists to study their metabolism in humans, safely and with unsurpassed accuracy.
«Our design incorporates conventional
silicon transistor switches to «turn
on» operations between qubits in a vast two - dimensional array, using a grid - based «word» and «bit» select protocol similar to that used to select bits in a conventional
computer memory
chip,» he added.
Unlike almost every other major group elsewhere, CQC2T's quantum computing effort is obsessively focused
on creating solid - state devices in
silicon, from which all of the world's
computer chips are made.
Using the new methods of micromachining, which borrow technology for making
computer chips to carve out and build up microscopic structures
on silicon wafers, Peter Gammel and his colleagues at Bell Labs / Lucent Technologies reduced three of the critical devices of a cell phone to Lilliputian size that will allow all the components of a phone to be constructed
on a single
chip.
Today, shrunk to just nanometres across and carved into beds of
silicon, these electrical
on - off switches mass in their billions
on every single
computer chip.
Like
silicon, graphene is a semiconductor, but the nano - sized ribbons could be used to pack much more processing power
on every
computer chip.
There he is working to create a
computer that will fulfill his boyhood vision — a new kind of
computer, based not
on the regimented order of traditional
silicon chips but
on the organized chaos of the human brain.
To improve the efficiency of waveguides — devices that guide light
on the surface of
silicon optical
computer chips — a complex balance must be struck.
These «organs
on a
chip» — so called for their resemblance to
silicon computer microchips — look nothing like the body parts they're meant to replicate.
The iPhone, for example, is made from commodities such as
silicon, iron, plastic, steel, and rare earth metals fashioned into
computer chips, screens, and so
on.
