TOKYO, Mar 17, 2022 - (JCN Newswire) - NEC Corporation (TSE: 6701) has developed the world's first LHZ scheme(1) unit cell facilitating scaling up to a fully-connected architecture using superconducting parametron(2) quantum bits (qubits). NEC has succeeded in demonstrating quantum annealing operations using these qubits, which will enable high accuracy calculations. Via this achievement, NEC has made further progress toward the production of a quantum annealing machine(3), which is a type of quantum computer.
Combinational optimization is important for finding solutions to complex social issues. It aims to find the optimal solution from an enormous set of potential choices. In 1999, NEC developed a superconducting qubit for use in gate-type quantum computers. Since then, NEC has applied the technology in the research and development of a quantum annealing machine using superconducting parametron qubits that can solve combinatorial optimization problems at high speed and with great accuracy.

NEC has developed a four qubit unit cell of the LHZ scheme. This enables scaling to multiple fully-connected logical qubits utilizing superconducting parametron and circuit coupling technology. NEC has achieved a world first by successfully solving small-scale combinatorial optimization problems via quantum annealing using this new technology. In another world first, NEC has also developed a three-dimensional structure technology that efficiently connects many LHZ scheme unit cells arranged in a tile pattern with external devices.

By replicating the unit cell in a tile pattern, it is possible to easily create a structure where many qubits are logically connected to each other, whilst maintaining the features of the superconducting parametron that allow it to perform calculations with high accuracy. NEC has made progress toward the realization of a quantum annealing machine that can solve large-scale and complex combinatorial optimization problems at high speed.

NEC is working to develop a quantum annealing machine using superconducting parametrons as a project(4) commissioned by the New Energy and Industrial Technology Development Organization (NEDO). NEC is currently conducting research and development to improve the integration of superconducting parametrons in a fully connected architecture, with the aim of realizing quantum annealing machines by 2023. NEC will use these results as building blocks to further accelerate the development of quantum computers.

(1) LHZ scheme: LHZ is an abbreviation for a technique proposed by Lechner, Hauke and Zoller. As the number of qubits increases, it becomes difficult in hardware to directly connect each qubit to each of the other qubits. To solve this problem, ParityQC proposed with LHZ a transformation that enables fully connected qubits to be obtained using qubits that are physically connected to only their nearest neighbours. A unit cell, composed of four qubits and a central coupling circuit connecting them can be replicated using a tile-like pattern.

(2) Superconducting parametron: A superconducting resonant circuit composed of Josephson junctions and capacitors which oscillates with different phases and can be used as a qubit. The lifetime of the qubit (which determines the upper limit of the time for which high-speed operation is possible) is an order of magnitude longer than that of magnetic flux qubits. It is expected that calculations performed within a fixed time period will have improved accuracy.
(3) Quantum Annealing Machine: A computer that exploits the laws of quantum mechanics to search for the minimum energy state of a cost function. The minimum energy state corresponds to the solution of the combinatorial optimization problem. The smallest unit to be calculated is a qubit. As the number of qubits increases and the connectivity between the qubits increases, larger and more complex combinatorial optimization problems can be solved.

A recently published Reuters poll suggests the European Central Bank (ECB) may wait until the last quarter of the year (Q4) to raise its first interest rate in over ten years. The poll’s author details that after the conflict in Ukraine, “fewer economists” predict the ECB will raise the benchmark bank rate earlier. Moreover, a […]

Singapore, Mar 7, 2022 - (ACN Newswire) - Infocus International Group is bringing back the highly recommended Carbon Capture, Utilisation and Storage (CCUS) online masterclass and it will be commencing live on the 5th of July 2022.
This course is intended for those in business, commercial and strategically focused roles within the energy sector; in particular those responsible for environmental matters, business sustainability and business transformation in areas such as oil & gas, hydrogen and industrial energy usage.

Attendees will leave with a clearly explained and independent perspective on how, where and why CCUS is happening now and could grow in future - covering the range of technological solutions and business drivers, including policy. In addition to reviewing existing CCUS approaches, the course will highlight new opportunities and integrated value creation possibilities through carbon utilisation. This will include how the fate of CCUS links to other aspects of the clean energy transition, such as clean hydrogen production, industrial decarbonisation and the transition away from oil & gas.

Past attendee from Solar Clear shared, "This course has provided a good understanding and cleared all false expectations about CCUS and of its cross entanglement to the hydrogen sector and the importance of both for decarbonising the world's (or part of the world's) economy."

"The up-to-date information was provided in course. The materials were available before the course, that is why it was possible to think about questions. The course materials were logically structured. The lecturer was highly professional. The organization of course was wonderful. Thank you very much!," said a past participant from Latvenergo.

Course Sessions:
- Carbon sources & capture technologies
- Carbon storage, transport & utilisation
- Hydrogen, carbon and industrial clusters
- Growing CCUS: scalability, markets, policies & strategies

Benefits of Attending:
- Understand the most challenging aspects of the clean energy transition & the role of CCUS in addressing them
- Examine the various technological aspects of the CCUS value chain, from capture through to storage and/or utilisation pathways
- Discuss the key economic and policy variables which will determine how CCUS plays out in different markets
- Review up-to-date examples of projects and strategies from around the world, and evaluate the lessons from them
- Learn the dynamics of the new competitive environment, including the risks of "business as usual" and the importance of industrial clusters in CCUS deployment
- Identify approaches to sustainable strategic planning and new business opportunity assessment
