What Is the Quantum Computing Race and Its Implications?

TL;DR

The race to harness quantum computing is a two-way contest between the United States and China, with IBM leading the technical charge from its research facility where it built the Quantum System 2 and its 133-qubit Heron chip. Unlike standard computers that check every path in sequence, quantum machines use qubits held in superposition to weigh all possibilities at once, promising breakthroughs in medicine, materials, and physics but also the power to decrypt internet communication. Read on for how the machine works and what's at stake.

Questions & Answers

Q: What is the fundamental difference between a quantum computer and a classical computer?

A standard computer calculates using billions of on/off switches called bits that work in sequence, so solving a maze means checking every possible path one by one until it finds the answer. A quantum computer uses quantum bits, or qubits, which can be held in a superposition where they are both on and off at the same time. This lets a series of qubits consider all possible routes at once, delivering the answer almost instantly.

Q: How much faster can a quantum computer be than today's supercomputers?

According to the video, a quantum computer could complete in minutes a computation so complex that today's supercomputers would take millions of years to finish. This speed comes from qubits solving many calculations simultaneously rather than one at a time.

Q: What is IBM's Quantum System 2 and the Heron chip?

IBM Quantum System 2 is IBM's newest experimental quantum machine, shown by quantum scientist Olivia Lanes. The large gold structure people often mistake for the computer is actually a cooling system; the actual computer is the tiny Heron chip, which holds the 133 qubits that carry out the computation.

Q: Why does the quantum chip have to be kept so cold?

The qubits are extremely fussy: any outside energy, including heat, can change the qubit's state in an unintended way and break the algorithm, giving the wrong answer. To preserve this delicate quantum state, the tangle of gold-plated pipes chills the chip to just above absolute zero, making it orders of magnitude colder than the cosmic microwave background and effectively the coldest thing in the known universe.

Q: Why is quantum computing a threat to encryption and internet security?

The video warns that quantum computers will come with the ability to decrypt all internet communication. This is the dark side of the technology and a key reason experts describe a quantum arms race, since whoever leads could put international security under threat.

Q: What scientific breakthroughs could quantum computing enable?

Because nature itself is quantum mechanical at the molecular and atomic level, a quantum computer can simulate those interactions in a way classical computers only crudely approximate. This opens the door to designing drugs, materials, and batteries at the level of atoms, with promised advances in material science, medicine, and fundamental physics.

Q: When does IBM expect to unlock quantum computing's full potential?

IBM says it will unlock quantum's full potential by 2033. The company frames this as an expensive, long-term endeavor, noting it spends close to $7 billion, and quantum computers cannot yet outperform a supercomputer on useful calculations because getting even a handful of qubits to give reliable answers is phenomenally difficult.

Summary & Key Takeaways

• Quantum computing is a groundbreaking technology that promises to revolutionize various industries by enabling unprecedented computational power. This potential has sparked a global race, primarily between the U.S. and China, to achieve quantum supremacy and leverage its capabilities for economic and strategic advantages.

• IBM is leading the charge in quantum research, investing billions in developing quantum computers that utilize qubits for parallel computation. However, quantum computing also poses significant risks to current encryption methods, potentially enabling rapid decryption of all internet communication.

• China's substantial investment and patent holdings in quantum technology underscore its ambition to dominate the field. The U.S. is countering with increased R&D investments, recognizing the strategic importance of leading in quantum technology. Despite the competitive landscape, quantum advancements offer opportunities for global collaboration.
