Rutgers University of New Brunswick researchers have produced a new material known as a “Quantum Anomalous Hall Insulator”. Using multiple layering and combinations of chromium, vanadium, antimony, bismuth, and tellurium, the insulator was etched into the Hall bar shape manually. Further enhancing efficiency was a 15nm layer of gold to reduce electrical interference in the system
Research teams at Yokohoma University have moved quantum computing efforts closer to realizing controllable quantum systems. Microwaves have been known to cause interference in quantum gates under certain conditions, creating difficulty in quantum gate manipulation. By eliminating the microwave-induced interference, the group was able to improve control of the quantum gate in diamonds at room temperature without a magnetic field. This step is an enabler of sustained quantum memory which lends to quantum repeaters. A needed piece of hardware to developing a quantum network.
niversity of Central Florida and the U.S. Air Force Office of Scientific Research, amongst others, have stumbled upon a material which has a variety of quantum properties. Though early in the study of the hafnium, tellurium, and phosphorus material, the research finds Hf2Te2P has multiple electron patterns; ergo, multiple quantum properties. Being a non-silicon-based material, future study will determine if Hf2Te2P is indeed a breakthrough in quantum computing necessary material.
One of the most anticipated uses for quantum computing was to solve the ‘recommendation problem’; previously believed unsolvable with classical systems. Now, an 18 year old whiz-kid has proven otherwise.
Using qubits to counter qubit errors without generating more errors or collapsing “the entire enterprise.”
Decoherence is a grind on the effort to move quantum computing forward. Efforts to overcome decoherence, the loss of a coherent state, is a field of much research. Scientists at MIT have published a method to help resolve part of the issue which is a failing to correct the dominant noise type in quantum sensors. Their method exploits spatial correlations involving qubits and tailors the error-corrections to the “noise” vice temporal correlations between signal properties and noise.
Australia, in collaboration with U.S.A.’s Purdue University, surged forward with controlling qubits individually on silicon chips. The ability to control qubits singly is seen paramount to moving ahead in making quantum computing a reality. Additional positive findings were error-reductions in the system due to the ability to control qubits individually when in proximity to each other. This brings quantum computing one step closer to complex computations involving entangled states.
This work argues quantum computing will not destabilize our world. Two foundational points are made: “Uncertainty [is] an important cause of war” and “institutions [are] an important source of information”. Though requiring some time to read and digest, the argument put forth in this working paper is worth the time for those whose mindset is strategic.
Quantum computing, artificial intelligence (AI), Big Data are all part of the transformative technologies blossoming today. Some call these “disruptive technologies”. Though they may look disruptive at first, history shows technology takes time to change the way we humans operate.
International Business Machines (IBM), also known as “Big Blue”, has been awarded nearly $750 million U.S. dollars by the Australian government. Quantum computing is ear-marked in the spending. Australia anticipates bringing artificial intelligence, quantum computing, and blockchain into the government’s fold. The quest is to be one of the top digital governments within the next ten years. This deal serves to reduce cost while speeding up the arrival of the Australian government’s digital transformation.
