6 things you really should know about Quantum they didn't teach you in high school PE.

Quantum computing is taking up a lot of airspace in today’s conversations, so we at Persel Group are diving in.

This is new to us too, we welcome additional explanations or simpler ways of breaking it down. Here’s to some quantum knowledge.

What is quantum computing?

Think of a regular computer as a librarian who finds books one at a time by checking the shelves.

A quantum computer, on the other hand, is like a librarian who can look at every book in the library at the same time—making it incredibly fast at solving certain problems.

Instead of using bits (1s and 0s) like normal computers, quantum computers use qubits (quantum bits), which can exist as both 1 and 0 at the same time due to a phenomenon called superposition.

This allows quantum computers to process vast amounts of data much faster than traditional computers.

Key quantum computing terms

Qubit

A qubit is the fundamental unit of quantum computing.

Unlike classical bits, which are either a 1 or a 0, a qubit can exist in both states simultaneously due to superposition.

This enables quantum computers to perform multiple calculations at once, vastly increasing processing power.

Qubits can be made using superconducting circuits, trapped ions, or even topological materials like those in Microsoft’s Majorana 1 chip.

Superposition

A quantum property where a qubit exists in multiple states at once.

If a classical bit is like a coin that lands on heads or tails, a qubit in superposition is like a spinning coin that is both heads and tails at the same time.

This allows quantum computers to evaluate multiple possibilities simultaneously, drastically reducing computation time.

Entanglement

A phenomenon where two or more qubits become interconnected, meaning the state of one instantly affects the other, no matter how far apart they are.

This is a key feature of quantum computing’s power, as entangled qubits work together in complex calculations, sharing information instantaneously.

Einstein famously called it "spooky action at a distance."

Quantum speedup

The exponential increase in processing power that quantum computers provide over classical ones.

Because quantum systems can evaluate multiple solutions simultaneously, they can solve problems in seconds that would take today’s supercomputers thousands or even millions of years.

This speed is particularly useful in fields like cryptography, optimization, and scientific simulations.

Topological qubit

A type of qubit that is more stable and resistant to errors due to its unique mathematical properties.

Microsoft’s Majorana 1 chip leverages topological superconductors to create these qubits, reducing the need for error correction and making large-scale quantum computing more feasible.

Unlike traditional qubits, which are highly fragile and error-prone, topological qubits store information in a way that naturally resists interference.

Quantum error correction

One of the biggest challenges in quantum computing is maintaining qubit stability. Traditional qubits are extremely sensitive to their environment, leading to computational errors.

Quantum error correction techniques, like surface codes and topological qubits, are designed to counteract these errors and make quantum calculations more reliable.

How is this different from AI?

AI is like a really smart assistant that finds patterns and makes decisions based on data.

Quantum computing, however, is like giving AI a superpower allowing it to solve incredibly complex problems that classical AI models simply can’t handle today.

Quantum AI will allow computers to process and analyze information in ways that are currently impossible, revolutionizing fields like drug discovery, climate modeling, and material science.

Why does quantum computing matter?

Quantum computers won’t replace regular computers but will transform industries like:

• Healthcare: Simulating molecules to discover new medicines faster and tailor treatments at the molecular level.
• Environment: Creating materials that can break down plastics or reduce carbon emissions by simulating chemical reactions at an atomic scale.
• Technology: Designing materials for self-healing airplane wings, ultra-fast batteries, and superconductors that operate at room temperature.
• Cybersecurity: Quantum computers could break traditional encryption but also create quantum-safe cryptography to protect sensitive data.
• Supply Chain & Logistics: Quantum optimization could revolutionize logistics, reducing fuel costs and improving global supply chain efficiency.

While Microsoft is pioneering topological qubits, other major players are tackling quantum computing using different methods:

• Google: Their Sycamore processor achieved quantum supremacy in 2019, performing a calculation in minutes that would take a classical supercomputer thousands of years.
• IBM: Developing superconducting qubits with their Eagle and Osprey processors, aiming to scale to a 1,000-qubit machine soon.
• Intel : Working on silicon-based qubits, leveraging their semiconductor expertise to make quantum chips more manufacturable.
• Quantinuum & Atom Computing: Partnering with Microsoft to push forward qubit reliability and quantum applications.
• D-Wave: Specializing in quantum annealing, a different approach to quantum computing that excels in optimization problems.
• China & Europe: Various governments are heavily investing in quantum research, with China’s Jiuzhang quantum computer achieving notable breakthroughs in photonic quantum computing.
• SandboxAQ: A Google spinout that focuses on post-quantum cryptography and AI-powered quantum simulation. They are helping enterprises prepare for the post-quantum era with quantum-safe security solutions.

So, what’s next?

Microsoft’s Majorana 1 chip brings quantum computing closer to reality by making qubits more reliable and scalable.

This means that in a few years (instead of decades) quantum computers could be tackling real-world challenges, transforming science, medicine, and technology forever.

It’s still early, but one thing is clear: Quantum computing is no longer science fiction. It’s coming.
