 Quantum computing has lots of potentials, but it also presents a significant challenge. Even though quantum computers don’t have the power to break most encryption now, we should still develop solutions that are safe from future threats. Building a quantum computer is a challenging and expensive process.

What is quantum computing and how do we use it?

A new era that we talk about is all here popularly known as “Quantum Computing”. It is a type of computer technology that is basically run by the core factors of quantum physics. The base of quantum physics is rooted in the ability to use subatomic particles which can exist in more than one state. As an example, ( using 1 and 0 at one time). With this new way of computing, such tasks can be done exponentially faster.

This quantum computing system is based on emergent principles of quantum physics which enable them to do computations at speeds much faster than conventional computers and at less energy consumption.

It was discovered that problems could be solved more quickly with quantum computers, than with classical computers. However, quantum computing uses qubits that can exist in more than one state. For example, a particle could both exist as a 1 and 0 simultaneously. Quantum computing is a new way of computing that uses quantum physics.

How quantum computing works and why is it faster

Quantum computing has the potential to revolutionize existing technology, and many popular tech companies are beginning to invest in the sector.

Unlike a classical computer, which has only 1s and 0s, quantum computers can be both 1 and 0 at the same time. This means that as qubits are linked together, there is exponentially more processing power.

Classical computers are the best for completing daily tasks and everyday jobs. However, quantum computers are great for simulations and data analysis because of their high level of accuracy and faster processing time. While a quantum computer might not make your Microsoft Word run better or faster, it can speed up the process of solving difficult problems.

For example, it may help speed up machine-learning training or the creation of batteries that are more energy efficient. It also helps to detect things like missiles and aircraft and can make information more secure by ensuring encryption needs less power.

What is the superposition in quantum?

Quantum computers have their way of searching problems, typically something nobody else can do. They use a process called entanglement and something called superposition, which is how they are different than other computers.

Quantum objects can exist in two states simultaneously. This can happen with an electron, which is in the lower energy level (ground state) and the first excited state for instance. Using superposition, you can prepare the electron in both states before measurement; when measured, it will appear to be in one or the other of these states.

Standard computing bits are what enable the on or off switches, or 0 and 1, to be turned on and off. The superposition, or state of being both on and off at different points in time, can be manipulated by quantum operations during computations.

Information Security in the Era of Quantum Computing

Quantum computers can solve complex algorithms and equations that classical computers cannot. One type of encryption used today is called RSA. The largest quantum computer right now is 53-qubit, so we still have some time left before we can break the encryption.

With quantum computing on the horizon, the current encryption techniques used by our data protection systems will be rendered ineffective. As technology developed, we need to take necessary measures to protect against the possibility of a data breach.

Role of Singapore in Quantum Computing

Singapore is investing in new programs to strengthen its quantum computing skills. Its newest initiatives will likely bolster the country’s skills in quantum computing, ensure encryption, and keep it protected from brute force attacks.

The Singapore government announces its plans to spend SG$34 million over three years on three national platforms in the Quantum Engineering Programme. It will allocate wage increments to universities and help fund fellowships, among other initiatives.

There is a shortage of skilled professionals in the emerging industry and would like to build collaborations, train new talent, and look at international opportunities. The National Supercomputing Center for China (NSCC) would provide the power needed to develop quantum computing projects and learn how to use them. Speculation is there on how quantum computing can help improve various industries and how researchers can explore how it might work.

Heng Swee Keat said that Singapore needed to remain vigilant as the country faced intensifying threats. Heng says more information is necessary to deal with threats that continuously look to exploit new gaps. Cyber security measures like quantum technology are being used as a potential “game-changer”. Quantum technology research is paramount to shaping the future.

How does Google see It?

IBM is investing in quantum computing technology, which they expect to advance in the coming years. Google has also designated an AI campus in California to meet its 2029 deadline.

There are no commercialized quantum computers on the market currently, but there is development and interest. Quantum computing is still in the business phase so there may be a Google-made service eventually. Microsoft’s Azure Quantum platform provides businesses with access to quantum technologies, as Google does not.

What is the cost of quantum computing?

The first quantum computers cost billions, but Shenzhen SpinQ Technology is now selling them to consumers for $5000.

How quickly can a quantum computer execute tasks?

IBM Summit performs calculations at a rate of 10,000 years to solve one problem. Google’s quantum computer, though disputed by IBM, can complete a calculation 200 seconds, which would take IBM Summit 2.5 days to do.

As we rely more and more on the digital world, cyber security becomes increasingly important. Cyber threats are rising, so staying ahead of them is crucial. Del Chiaro is excited about Bell Labs and its new fabless foundry in India because he sees that it is tapping into the country’s manufacturing capabilities to develop products. He believes that this will alleviate “real-world challenges” by creating quantum devices with industry partners.
