Quantum Computing for Energy Grid Optimization

While voltage in our everyday macro scale is measured as a continuous variable, quantum mechanics tells us that at the subatomic scale this is not really the case. Rather, by all experimental accounts, subatomic particles appear to occupy only discrete energy states. This means that an electron and a photon can occupy some energy states, and not others. This contravenes our intuitions about physical objects being able to occupy any continuous energy state. For example, while we typically think of time as a purely continuous variable that’s infinitely divisible, this is starkly not the case for the energy states of subatomic particles.

“Quantum computing may have a profound impact on the securities industry, whether for larger and more well-resourced firms seeking to leverage quantum advantage or for firms of all sizes preparing to defend against attacks on present-day cryptography,” the report said. The technology could supercharge artificial intelligence (AI) applications too, it suggested. (a)  In addition to promoting quantum leadership and mitigating the risks of CRQCs, the United States Government must work to safeguard relevant quantum R&D and intellectual property (IP) and to protect relevant enabling technologies and materials. Protection mechanisms will vary, but may include counterintelligence measures, well-targeted export controls, and campaigns to educate industry and academia on the threat of cybercrime and IP theft. These plans shall be expeditiously developed and be designed to address the most significant risks first. This project shall develop programs for discovery and remediation of any system that does not use quantum-resistant cryptography or that remains dependent on vulnerable systems.

Then, the investigation of quantum computing begins with a single qubit and quantum gates acting on it, first using geometry and elementary algebra, and later using linear algebra. Computer algebra systems are utilized, and code for both Mathematica and SageMath is included. After one qubit, multi-qubit systems are covered, including how quantum computers add numbers, universal gate sets, and error correction. After this, readers learn how to program quantum circuits on actual quantum processors using IBM Quantum Experience.

In this combined state, the proportion of each configuration is determined by a complex number. Because this system allows atoms to be packed relatively tightly together, Atom Computing argues that the system is well-positioned to scale rapidly. Unlike in systems like transmons, where small differences in device fabrication lead to qubits with small variations in performance, every trapped atom is guaranteed to behave the same. And, since atoms don’t engage in cross talk unless manipulated, it’s possible to pack a lot of them into a relatively small space.

In this landscape, quantum computing has transcended the realm of science fiction and emerged as a potent tool for organisations to enhance operations and boost efficiency dramatically. But once Finland has a 300-qubit quantum computer, it will probably be able to solve useful problems. Researchers expect to use it to solve problems in materials science, performing molecular simulations much faster than can be done on a traditional computer. They also hope to also use it to solve optimisation problems, using the hybrid computing approach to have the supercomputer hand off tasks to the quantum computer.

Quantum Computers In Development

In that same year the
first realisation of a quantum logic gate was done in Boulder,
Colorado, following Cirac and Zoller’s proposal. In 1996, Lov
Grover from Bell Labs invented a quantum search algorithm which yields
a provable (though only quadratic) “speed-up” compared to
its classical counterparts. A year later the first model for quantum
computation based on nuclear magnetic resonance (NMR) techniques was
proposed. This technique was realised in 1998 with a 2-qubit register,
and was scaled up to 7 qubits in the Los Alamos National Lab in
2000.

We’ve known since the ’90s that they could zip through the math underpinning the encryption that secures online banking, flirting, and shopping. Quantum processors would need to be much more advanced to do this, but governments and companies want to be ready. The US National Institute of Standards and Technology is in the process of evaluating new encryption systems that could be rolled out to quantum-proof the internet.

But ask anyone in the industry, they’ll probably say there’s already a hub here. Quantum traces its local roots to the 1950s when the National Institute of Standards and Technology picked Boulder for a research facility. NIST, which needed quantum measurements because they need to measure the most precise and sensitive things in the world, later partnered with the University of Colorado to create the Joint Institute for Laboratory Astrophysics in 1962. You don’t need a degree in quantum engineering to work in a cutting-edge quantum lab in Colorado, which was just named a U.S.

The whole thing needs to be set up inside a freezer cooled down to almost absolute zero. Program quantum oracles and queries with Q#, and use them to solve problems. First, accepted explanations of the subatomic world turned out to be incomplete. Electrons and other particles didn’t just neatly carom around like Newtonian billiard balls, for example.

This technology is widely expected to solve valuable problems that are unsolvable using any known methods on classical supercomputers. Scientists and engineers anticipate that certain problems that are effectively impossible for conventional, classical computers to solve will be easy for quantum computers. Quantum computers are also expected to challenge current cryptography methods and to introduce new possibilities for completely private communication. IBM has spent years advancing the software that will be necessary to do that useful work. It is open-source, Python-based, and by far the most widely-used quantum SDK in the world — useful for executions both on IBM’s fleet of superconducting quantum computers and on systems that use alternative technologies like ions trapped in magnetic fields. Complex problems are problems with lots of variables interacting in complicated ways.

Google starts its new quantum hardware lab and hires the professor behind some of the best quantum computer hardware yet to lead the effort. Superposition is the counterintuitive ability of a quantum object, like an electron, to simultaneously exist in multiple “states.” With an electron, one of these states may be the lowest energy level in an atom while another may be the first excited level. If an electron is prepared in a superposition of these two states it has some probability of being in the lower state and some probability of being in the upper.

There is an older tradition of
analog quantum simulation, however, wherein one utilises a
quantum system whose dynamics resemble the dynamics of a particular
target system of interest. The quantum computer might be the theoretician’s dream, but as
far as experimentalists are concerned, its realisation is a nightmare. The problem is that while some prototypes of the simplest elements
needed to build a quantum computer have already been implemented in
the laboratory, it is still an open question how to combine these
elements into scalable systems (see Van Meter and Horsman 2013).

Researchers there compute with qubits obtained using the “trapped ion” approach, arranging atoms of the rare-earth element ytterbium into a tidy row, then manipulating them with a laser. Jungsang Kim, IonQ’s C.T.O., told me that his ion traps maintain entanglement better than Google’s processors, but he admitted that, as more qubits are added, the laser system gets more complicated. In 2001, experimental physicists at I.B.M. tried to implement the algorithm by firing electromagnetic pulses at molecules suspended in liquid. Implementing such precise controls at the subatomic scale remains a fiendish problem. A full-scale quantum computer could crack our current encryption protocols, essentially breaking the Internet.
