Quantum technology empowers silicon chips with performance 100 times that of conventional chips.

In recent years, computer systems have relied on Silicon processors and memory chips, arranged on a single layer. These components are interconnected through a complex system of wires, allowing data to be computed on the processor and then stored on the memory chip.

However, challenges arise when this configuration sends digital signals along a longer path than its ideal level, leading to data transmission bottlenecks and excessive data attempting to simultaneously reach similar circuits. Both issues can be addressed by stacking processors and memory chips. The stacked chip solution is also applied in managing the production of 16 Terabyte hard drives.

To manufacture a Silicon chip, it needs to be heated up to 1800 degrees Fahrenheit, an incredibly challenging task. To overcome this difficulty, manufacturers have had to produce individual Silicon chips, stack them together, and connect the necessary thousands of wires to provide the best, most complete solution meeting human usage needs.

Now, a group of researchers at UNSW Sydney (University of New South Wales) has demonstrated that 'Qubit spin'—the properties of electrons representing basic units of information in quantum computer applications—can hold information for up to two milliseconds. Termed the 'perfect coupling time,' this period, during which Qubits can be controlled in increasingly complex calculations, is more than 100 times longer than previous benchmarks in the same quantum processor.

Qubit spin quantum computers manipulate the spin of charge carriers (electrons and electron holes) in semiconducting devices. Proposed by Daniel Loss and David P. DiVincenzo in 1997, the Qubit spin quantum computer utilizes the intrinsic spin-½ degree of freedom of individual electrons confined in quantum dots as Qubits.

To date, Qubit spin has been realized by depleting locally two-dimensional electron gases in semiconductors such as gallium arsenide, silicon, and germanium. Qubit spin has also been implemented in graphene. In quantum computing, the more spins you can maintain, the better the chances of preserving information during computations. When Qubit spins stop spinning, computations collapse, and the values represented by each Qubit are lost. The concept of extended coherence was experimentally confirmed by quantum engineers at UNSW in 2016.

Manufacturing quantum chips and quantum computers in the laboratory takes a considerable amount of time and incurs substantial costs. Despite this, the quantum computing industry has achieved early successes. It's a race among giants such as Intel, Google, IBM, Microsoft, and others.

For instance, Intel has introduced the Tangle Lake 49 Qubit quantum chip, the most powerful in the world. Google has also unveiled the most powerful quantum chip to date, the Bristlecone 72 Qubit. IBM, another industry giant, has successfully developed a 50 Qubit computer. In early 2019, IBM also announced its commercially powerful quantum computer named IBM Q System One.

Expectations for quantum computers may be ahead of reality, but the potential of this field remains vast. The Boston Consulting Group in the U.S., in July, forecasted that quantum computers could generate an annual value equivalent to $10 billion by 2030 and rise to $850 billion by 2040. Quantum technology, in general, is a lucrative domain, and individuals or businesses owning it will dominate the digital technology era.

Quantum technology in sensor production harnesses the sensitivity of quantum states, detecting light, gravity, and magnetic fields. This enhances image quality and reproduces color at the most authentic and sharpest levels possible.

Quantum technology ensures absolute information security. Quantum cryptography secures information transmitted through optical communication, providing unparalleled data security. Unlike traditional encryption methods susceptible to powerful computers or skilled hackers, quantum technology locks encrypted content exclusively for authenticated recipients through unique codes.
