Quantum Computing Is Almost here & It’s Going Transform the future

Quantum Computing Is Almost here

Quantum Computing is close at hand.

According to Dario Gil, the chief operating officer of IBM Research, and Chad Rigetti, the founder of Rigetti Computing, the era of quantum computing is approaching rapidly. They express the belief that within approximately three years, quantum computers will surpass the capabilities of today’s computers, delivering superior performance.

Rigetti emphasizes that quantum computing has transitioned from being solely a field of research to becoming an established discipline and enterprise in the realm of engineering. The focus now is on developing practical solutions that are better, faster, and more cost-effective than what can be achieved with classical computing methods.

The Chinese government is building a $10 billion National Laboratory for Quantum Information in Anhui province, which borders Shanghai and is slated to open in 2020. Meanwhile, the U.S. public research into quantum computing is running at around $200 million per year.

Cloud Quantum Computing

Rigetti explains that users can utilise our software development kit to write their own quantum applications on their personal devices. The program is then sent to a compiler, which initiates an optimization kit running on both a quantum computer and a classical computer. This architectural setup is crucial for achieving quantum advantage.

IBM currently has over a million chips performing numerous quantum operations as requested by users in more than 100 countries worldwide.

Rigetti suggests that in an era focused on cloud computing, there may not be sufficient economic incentives to develop miniaturized quantum environments for laptops. However, the commercialization of quantum computing will have far-reaching implications for everyone, regardless of location.

He asserts that quantum computing will revolutionize the world within our lifetime, whether that timeline is two or five years. Technology will redefine every industry and have an impact on every market. Consequently, every major company will be involved in some capacity in the quantum computing space.  Full Story

IBM makes 20-qubit quantum computers

Dario Gil, IBM Research VP of AI and IBM Q, says the increased number of qubits is only part of the story. The more Qubits you deal with, the more complex the qubit interactions become because they interact in entanglement. If you have more qubits, but there is a high error rate as they interact, then they might not be any more potent than 5 qubit machine with a lower error rate. He says that IBM researchers have achieved the higher qubit number with low error rates, making them highly useful to researchers.

“We have more qubits and less errors, which is combined to solve more problems,” Gil said.

More Qubits with fewer errors

According to Gil, the progress in quantum computing is an incremental process, and the recent announcement marks a step forward on this journey. He emphasizes that even the current capabilities of quantum computers are already quite powerful. With the latest release and enhancements made to the QISKit, IBM’s software development kit for programming quantum computers, they can continue advancing the technology. However, Gil cautions that quantum computing development will not happen overnight.

IBM envisions potential applications of quantum computing in fields such as medicine, drug discovery, and materials science as the technology advances and becomes better understood.

Gil also mentions that IBM is collaborating with standards bodies to develop encryption algorithms for post-quantum computing. While achieving this goal is still a long way off, they are aware of the significance of the challenges involved and are actively working to address them.  Full Story

Serious quantum computers are finally here.

“The biggest boost quantum information theory got was from Feynman,” Bennett told me. “He said, ‘Nature is quantum, goddamn it! So if we want to simulate it, we need a quantum computer.’”

IBM’s quantum computer

A highly promising machine, located near Bennett’s office, is being developed to manipulate and generate qubits, which are crucial for quantum computers to store information. Currently, engineers are focusing on creating a version of the computer with 50 qubits. While simulations of basic quantum computers can be run on conventional computers, it becomes extremely challenging around the 50-qubit mark. This implies that IBM is approaching the stage where a quantum computer could solve problems beyond the capabilities of classical computers, known as achieving quantum supremacy.

According to Robert Schoelkopf, a Yale professor and the founder of Quantum Circuits, if 50 or 100 qubits were to function effectively and be fully error-corrected, they could perform calculations that are unimaginable for classical machines, both currently and in the future. However, it’s important to note that quantum computing also carries the risk of exponential failures and errors.

Quantum Computing Is Almost here; even imperfect Quantum machines could still be useful.

In a notable achievement, Gambetta and his team at IBM utilized a seven-qubit quantum machine to simulate the intricate arrangement of beryllium hydride, making it the most intricate molecule ever modelled using a quantum system. While the long-term objectives of utilizing quantum computers to develop superior solar cells, more effective medications, and catalysts for clean fuel production are still distant, Gambetta suggests that valuable outcomes could be obtained by combining an error-prone quantum machine with a classical computer.  Full Story
