More news on Qubits that are surprisingly intrinsically resilient to noise.


While a classical bit found in conventional electronics exists only in binary 1 or 0 states, the more resourceful quantum bit, or ‘qubit’ is represented by a vector, pointing to a simultaneous combination of the 1 and 0 states. To fully implement a qubit, it is necessary to control the direction of this qubit’s vector, which is generally done using fine-tuned and noise-isolated procedures.

Researchers at the University of Chicago’s Institute for Molecular Engineering and the University of Konstanz have demonstrated the ability to generate a quantum logic operation, or rotation of the qubit, that — surprisingly — is intrinsically resilient to noise as well as to variations in the strength or duration of the control. Their achievement is based on a geometric concept known as the Berry phase and is implemented through entirely optical means within a single electronic spin in diamond.

Their findings were published online Feb. 15, 2016, in Nature Photonics and will appear in the March print issue. “We tend to view quantum operations as very fragile and susceptible to noise, especially when compared to conventional electronics,” remarked David Awschalom, the Liew Family Professor of Molecular Engineering and senior scientist at Argonne National Laboratory, who led the research. “In contrast, our approach shows incredible resilience to external influences and fulfills a key requirement for any practical quantum technology.”

Measuring entanglement — the amount of entanglement between states corresponds to the distance between two points on a Bloch sphere.

To do this, the scientists turned the difficult analytical problem into an easy geometrical one. They showed that, in many cases, the amount of entanglement between states corresponds to the distance between two points on a Bloch sphere, which is basically a normal 3D sphere that physicists use to model quantum states.

As the scientists explain, the traditionally difficult part of the math problem is that it requires finding the optimal decomposition of mixed states into pure states. The geometrical approach completely eliminates this requirement by reducing the many possible ways that states could decompose down to a single point on the sphere at which there is zero entanglement. The approach requires that there be only one such point, or “root,” of zero entanglement, prompting the physicists to describe the method as “one root to rule them all.”

One thing that will remain with tech for many years is jobs in cyber security — even with the layer of security that Quantum technology brings in the next 10 years; there is always a migration and retirement state that can (depending on the business and systems involved) could go on for years after Quantum platforms and networks are installed.


Then in December, aided and abetted by a Republican-controlled Congress, he eradicated those minor restrictions and replaced mindless austerity with clueless profligacy.

It proposes lifting the limits entirely from 2018. “It adheres to last year’s bipartisan budget agreement, it drives down the deficit, and includes smart savigs on health care, immigration and tax reform”.

Even with the increased taxes, Obama’s budget projects sharply higher deficits in coming years, totaling $9.8 trillion over the next decade.

Nano Satellite could be interesting and even expanded upon especially as we look to expand the usage of Quantum Technology across various wireless devices in the future as well as microbot technology to enable connectivity to the cloud and other wireless devices.


The nano-satellite, which is among ISRO’s important missions, will monitor air pollutants that pollute cities including Delhi, Lucknow, Amritsar and Allahabad.

The nano-satellite will weigh 15kg and placed 500 km above the earth.

SAC director Tapan Misra told ET the mission is designed to cover, each day, up to 50,000 sq km area of the country’s 32.87 lakh sq km.

This agreement places Oxford in a very nice position.


Quantum transport measurements are widely used in characterising new materials and devices for emerging quantum technology applications such as quantum information processing (QIP), quantum computing (QC) and quantum sensors. Such devices hold the potential to revolutionise future technology in high performance computing and sensing in the same way that semiconductors and the transistor did over half a century ago.

Physicists have long used standard electrical transport measurements such as resistivity, conductance and the Hall effect to gain information on the electronic properties and structure of materials. Now quantum transport measurements such as the quantum Hall effect (QHE) and fractional quantum Hall effect (FQHE) in two-dimensional electron gases (2DEG) and topological insulators – along with a range of other more complex measurements – inform researchers on material properties with quantum mechanical effects.

The ultra low temperatures and high magnetic fields provided by Oxford Instruments’ TritonTM dilution refrigerator make it a key research tool in revealing the quantum properties of many materials of interest. SPECS’ Nanonis Tramea QTMS is a natural complementary partner to the Triton, with its fast, multi-channel measurements.

Quantum gravity is a theory that has been the target of decades of study by physicists worldwide. If this idea is proven, it would tie together the General Theory of Relativity (which governs gravitational fields) with quantum mechanics, and the bizarro-world of subatomic particles.

Gravitational waves, produced by accelerating objects, ripple through space-time, according to most interpretations of the General Theory of Relativity penned by famed physicist Albert Einstein. Researchers at the Laser Interferometer Gravitational-Wave Observatory (LIGO) have announced they detected these disturbances in the fabric of time and space for the first time.
