# Quantum breakthrough could revolutionise computing

Over the next few years, researchers announced more ambitious experiments, adding

progressively greater numbers of qubits. Three years later, Google announced that it was hiring a team of academics (including University of California

at Santa Barbara physicist John Martinis) to develop its own quantum computers based on D-Wave’s approach. In March 2015, the Google team

announced they were “a step closer to quantum computation,” having developed

a new way for qubits to detect and protect against errors. With basic information processing units (qubits) governed by the exotic phenomena of quantum mechanics, quantum computers have the potential to be far better at performing certain calculations than today’s computers using conventional ‘bits’.

Though the specific interaction was relatively simple — current classical computers can model it too — future quantum computers are predicted to be able to simulate complex molecular interactions much more accurately than classical computers. Within healthcare, this could help speed up drug discovery efforts by making it easier to predict the effects of drug candidates. Quantum computing harnesses quantum mechanical phenomena such as superposition and entanglement to process information. By tapping into these quantum properties, quantum computers handle information in a fundamentally different way than “classical” computers like smartphones, laptops, or even today’s most powerful supercomputers. Sitting at the center of the quantum-centric supercomputer is advanced middleware, built for maximizing the performance of quantum applications running across parallelized, cloud-based, quantum- and classical-computational resources.

Quantum computing has the capability to sift through huge numbers of possibilities and extract potential solutions to complex problems and challenges. Where classical computers store information as bits with either 0s or 1s, quantum computers use qubits. Qubits carry information in a quantum state that engages 0 and 1 in a multidimensional way. Quantum computing employs the properties of quantum physics like superposition and entanglement to perform computation. Traditional transistors use binary encoding of data represented electrically as “on” or “off” states. Quantum bits or “qubits” can simultaneously operate in multiple states enabling unprecedented levels of parallelism and computing efficiency.

To implement such quantum operations on quantum computers, quantum programs are represented as circuits describing a sequence of elementary operations, called gates, that are applied on a set of qubits. One major difference between quantum and classical programming lies in a central principle of quantum mechanics—when it comes to measuring a quantum program’s results, the process is inherently probabilistic, or subject to random variation. Quantum computers process information in a fundamentally different way than classical computers. Traditional computers operate on binary bits but quantum computers transmit information via qubits.

The potential misuse of quantum power is driving the search for new quantum cryptography methods. Over the last three decades, quantum researchers have come up with a handful of ways to make qubits. The heart of a qubit is typically a very small particle — such as an atom, ion or electron — that due to its tiny size exhibits quantum properties. The fundamental component of this new technology is the qubit, a quantum version of the classical bit that everyday computers use to represent information. A classical bit has a value of either 0 or 1, and joining these bits into strings enables computers to represent information such as letters and numbers.

UC Berkeley is one of the many universities in California looking into quantum computing, mimicking the hub of activity by quantum companies in that area. The Berkeley Lab works on harnessing quantum computing to help solve real-world issues. With research topics ranging from quantum materials to even training the quantum workforce, UC Berkeley’s quantum computing masters program offers a multi-disciplinary approach. Lokhov notes that currently, in order to show that a new quantum algorithm works efficiently, one needs to give a mathematical proof.

The more

information you need to store, the more binary ones and zeros—and

transistors—you need to do it. Since most conventional computers can

only do one thing at a time, the more complex the problem you want

them to solve, the more steps they’ll need to take and the longer

they’ll need to do it. Some computing problems are so complex that

they need more computing power and time than any modern machine could

reasonably supply; computer scientists call those intractable

problems. The Pittsburgh Quantum Institute (PQI) at Carnegie Mellon University hosts over 100 members and workers to create a multidisciplinary quantum computing graduate program that involves engineering, business, philosophy of science, and other fields.

### Better together: Silicon qubits plus light add up to new quantum computing capability

The researchers can then use additional laser signals to set the trapped atom’s energy levels to represent quantum 0 or 1 states. In quantum computing, a qubit (/ˈkjuːbɪt/) or quantum bit is a basic unit of quantum information—the quantum version of the classic binary bit physically realized with a two-state device. A qubit is a two-state (or two-level) quantum-mechanical system, one of the simplest quantum systems displaying the peculiarity of quantum mechanics. Examples include the spin of the electron in which the two levels can be taken as spin up and spin down; or the polarization of a single photon in which the two states can be taken to be the vertical polarization and the horizontal polarization.

That would conceivably happen either through better engineering, discovering optimal circuit layout, and finding the optimal combination of components. That is, rather than having to perform tasks sequentially, like a traditional computer, quantum computers can run vast numbers of parallel computations. Quantum computing solves mathematical problems and runs quantum models using the tenets of quantum theory. Some of the quantum systems it is used to model include photosynthesis, superconductivity and complex molecular formations.

These experiments provide powerful insights on the quantum physics underlying material properties and can help show scientists how to design new materials with exotic properties. “The number of quantum states that are possible with only 256 qubits exceeds the number of atoms in the solar system,” Ebadi said, explaining the system’s vast size. With the Ocean software development tools and hybrid solvers, the complexity of quantum programming is abstracted away so users can focus on the business problem at hand.

## Quantum computing in artificial intelligence

In September 2019, the University announced the creation of the Princeton Quantum Initiative to foster exploration and education across the spectrum from fundamental quantum research to applications in areas such as computing, sensors and communications. The markets have been unkind to technology companies in recent months, though. IonQ is trading at half its debut price, and D-Wave has dropped about three quarters.

### Stable qubit is a prime candidate for universal quantum computer

The particles continue to fluctuate and move while the quantum computer measures and observes each particle. While it has its limitations at this time, it is poised to be put to work by many high-powered companies in myriad industries. However, China-based Shenzhen SpinQ Technology plans to sell a $5,000 desktop quantum computer to consumers for schools and colleges.
