Microsoft s Quantum Search for The next Transistor Microsoft is making a significant investment in creating a practical version of the basic component needed to build a quantum computer,
Microsoft has dedicated a quantum computing research lab, known as Station Q, on the campus of University of California,
A quantum computer should be able to complete calculations that are effectively impossible for any conventional machine today.
Although the Canadian company D-Wave Systems has sold several machines it says are quantum computers experts say there is still no definitive proof that they exploit quantum principles
and Jeff Bezos Bet on Quantum computing. Microsoft is not currently attempting to build a quantum computer. Rather, its research effort is aimed at developing a reliable version of the qubit, the key building block of a quantum computer.
Just like a transistor in a conventional computer, a qubit can switch between states that represent either a 1 or 0 of digital data.
But a qubit can also exploit quantum effects to reach a uperposition statethat is both 1 and 0 at the same time.
That would allow a quantum computer to process data many times faster than any conventional computer.
Researchers have built qubits of different designs and even used small numbers of them together for very basic calculations.
But none are able to maintain a superposition state very reliably, making them impractical for anyone hoping to build a computer of any size. e believe that current approaches will said never scale
Lee. Microsoft research focuses on a type of qubit known as a topological qubit that theory suggests would encode data in a much more robust way.
The theoretical basis of topological qubits was sketched first out at UC Santa barbara roughly eight years ago,
says Lee. Then around four years ago, Microsoft researchers led work to pose a series of key tests that could show
Work is now underway to actually build a working topological qubit. To support that effort,
Microsoft is already looking ahead to explore what could be done with a system of topological qubits once they are built. upposing that one day we have a quantum machine:
and many other applications and scientists believe it could eventually be used for quantum computers, a new generation of machines that use quantum mechanics to solve complex problems with extraordinary speed.

The revelation will enhance the continuous endeavors of researchers over the world to utilize semiconductor materials to construct quantum computing frameworks. consider this to be a truly imperative result for our long haul objective,

A single electron caught in a semiconductor nanostructure can structure the most fundamental of building blocks for a quantum computer.
Though, before practical quantum computers can be acknowledged, researchers need to create a versatile architecture that permits full control over individual electrons in computational arrays p

#D-Wave Breaks 1000 Qubit Quantum computing Barrier Today D-Wave Systems announced that it has broken the 1000 qubit barrier,
According to D-Wave, this is a major technological and scientific achievement that will allow significantly more complex computational problems to be solved than was possible on any previous quantum computer.
D-Wave quantum computer runs a quantum annealing algorithm to find the lowest points, corresponding to optimal or near optimal solutions, in a virtual nergy landscape.
Every additional qubit doubles the search space of the processor. At 1000 qubits the new processor considers 21000 possibilities simultaneously,
a search space which dwarfs the 2512 possibilities available to the 512-qubit D-Wave Two. n fact,
the new search space contains far more possibilities than there are articles in the observable universe. As the only manufacturer of scalable quantum processors, D-Wave breaks new ground with every succeeding generation it develops.
The 1000-qubit milestone is the result of intensive research and development by D-Wave and reflects a triumph over a variety of design challenges aimed at enhancing performance
Beyond the much larger number of qubits, other significant innovations include: A 1000 qubit processor will also be on display at the upcoming GEOINT conference in D-Wave booth,#10076.

#Researchers Build Memcomputing Prototype Over at Scientific Advances, a newly published paper describes a high-efficiency architecture called memcomputing.
That would have applications in quantum computing, an area of interest to the group because Jarillo-Herrero is a researcher in the NSF-funded Center for Integrated Quantum Materials.
When scientists develop a full quantum computer, the world of computing will undergo a revolution of sophistication,
But, before that happens, quantum physicists like the ones in UC Santa barbara's physics professor John Martinis'lab will have to create circuitry that takes advantage of the marvelous computing prowess promised by the quantum bit("qubit),
preserving the qubits'state (s) and imbuing the system with the highly sought-after reliability that will prove foundational for the building of large-scale superconducting quantum computers.
It turns out keeping qubits error-free, or stable enough to reproduce the same result time and time again,
is one of the major hurdles scientists on the forefront of quantum computing face.""One of the biggest challenges in quantum computing is that qubits are said inherently faulty
Julian Kelly, graduate student researcher and co-lead author of a research paper that was published in the journal Nature."
"So if you store some information in them, they'll forget it.""Unlike classical computing, in which the computer bits exist on one of two binary("yes/no,
"or"true/false")positions, qubits can exist at any and all positions simultaneously, in various dimensions.
"that gives quantum computers their phenomenal computational power, but it is also this characteristic which makes qubits prone to"flipping,"especially when in unstable environments,
and thus difficult to work with.""It's hard to process information if it disappears,
which several qubits work together to preserve the information, said Kelly. To do this, information is stored across several qubits."
"And the idea is that we build this system of nine qubits, which can then look for errors,
"he said. Qubits in the grid are responsible for safeguarding the information contained in their neighbors,
he explained, in a repetitive error detection and correction system that can protect the appropriate information
and store it longer than any individual qubit can.""This is the first time a quantum device has been built that is capable of correcting its own errors,
For the kind of complex calculations the researchers envision for an actual quantum computer, something up to a hundred million qubits would be needed,
but before that a robust self-check and error prevention system is necessary. Key to this quantum error detection
the actual original information that is being preserved in the qubits remains unobserved. Why? Because quantum physics."
The very act of measurement locks the qubit into a single state and it then loses its superpositioning power,
Therefore, in something akin to a Sudoku puzzle, the parity values of data qubits in a qubit array are taken by adjacent measurement qubits,
which essentially assess the information in the data qubits by measuring around them.""So you pull out just enough information to detect errors,
This development represents a meeting of the best in the science behind the physical and the theoretical in quantum computing--the latest in qubit stabilization and advances in the algorithms behind the logic of quantum computing."

A computational element made from such a particle--known as a quantum bit or qubit--could thus represent zero and one simultaneously.
If multiple qubits are entangled meaning that their quantum states depend on each other then a single quantum computation is in some sense like performing many computations in parallel.
With most particles entanglement is difficult to maintain but it's relatively easy with photons.
But any quantum computer--say one whose qubits are trapped laser ions or nitrogen atoms embedded in diamond--would still benefit from using entangled photons to move quantum information around.
