Quantum computing has long been one of the most exciting—and mysterious—fields of modern science. But Google’s recent claim that its new quantum chip, Willow, might be tapping into parallel universes has taken the intrigue to a whole new level.
Let’s break it down: What exactly is Google saying? How does quantum computing work? And are we really dealing with a technology that uses the multiverse to calculate? Whether you’re a quantum enthusiast or just someone curious about the next big thing, we’ll make it simple.
What Is Google Claiming?
Google recently announced that Willow, its 100-qubit quantum chip, performed a computation in under five minutes that would take the world’s fastest supercomputers 10 septillion years—that’s a number with 24 zeros! To put it into perspective, this is far longer than the age of the universe.
Here’s where it gets wild: Google suggests that Willow’s ability to solve this complex problem could mean it’s operating in parallel universes. The idea is based on a theory by physicist David Deutsch, who proposed that quantum computers might distribute their calculations across many universes simultaneously.
But before we get ahead of ourselves, let’s understand what quantum computing actually is—and how it’s different from the computers we use every day.
What Is Quantum Computing?
The Basics
Conventional computers use bits, which represent either a 0 or a 1—essentially on or off. These binary systems are the foundation of how every smartphone, laptop, and supercomputer works.
Quantum computers, on the other hand, use qubits (short for quantum bits). A qubit can be:
- 0,
- 1,
- Or both at the same time (this is called superposition).
This ability to be in multiple states at once allows quantum computers to perform many calculations simultaneously, making them incredibly powerful for specific types of problems.
How Does Willow Work?
Willow’s 100 qubits rely on a phenomenon called entanglement, where particles become linked so that the state of one instantly influences the other, even across vast distances. Using these entangled qubits, quantum computers like Willow can perform tasks that would overwhelm traditional supercomputers.
However, this doesn’t mean Willow is doing calculations we can use right now. For its demonstration, Willow solved a random distribution problem—a task designed specifically to showcase quantum speed but without practical applications.
The Multiverse Connection: Is It Real?
Here’s where things get really interesting—and speculative.
Physicist David Deutsch proposed in 1997 that quantum computers might draw on the power of parallel universes to perform their calculations. Essentially, each qubit could exist in one universe, doing its part of the computation, with the results combining across universes.
Google’s Hartmut Neven, the founder of Google Quantum AI, suggested that Willow’s astonishing performance could lend credence to this idea. However, many physicists prefer the Copenhagen interpretation of quantum mechanics, which posits that particles exist in all possible states until they’re measured—no multiverse required.
Why Are Experts Skeptical?
Despite the hype, many scientists are urging caution.
1. The Task Isn’t Practical
The problem Willow solved, generating a random distribution, is not something anyone needs in real life. Physicist Sabine Hossenfelder pointed out that this task was chosen specifically because it’s difficult for classical computers but doesn’t have practical value.
2. Similar Claims Were Debunked Before
In 2019, Google claimed to achieve “quantum supremacy” with a smaller chip, but competitors like IBM showed that classical computers could perform the same task in just a few days. It’s possible the same will happen with Willow’s claim.
Why Does This Matter?
Even if we’re not accessing parallel universes, quantum computing is still a revolutionary technology with massive potential.
What Could Quantum Computers Do in the Future?
- Drug Discovery: Simulating molecular interactions to develop new medicines faster.
- Cryptography: Breaking current encryption methods or creating unbreakable ones.
- Optimization Problems: Improving logistics, supply chains, and even traffic systems.
But there’s a catch: Scientists estimate that we’ll need about 1 million qubits to solve real-world problems effectively. Right now, Willow has only 100 qubits.
| Aspect | Current Quantum Computers | Future Quantum Computers |
|---|---|---|
| Number of Qubits | ~100 (Willow) | 1 million+ |
| Applications | Demonstrations and experiments | Real-world problem-solving |
| Timeline for Practical Use | Decades | Unknown, but likely decades away |
What’s Next for Google and Quantum Computing?
Google remains optimistic about scaling up Willow to become a truly useful quantum computer. In a blog post, Hartmut Neven called Willow “the most convincing prototype for a scalable logical qubit built to date.”
But for now, the multiverse claims are best seen as part of the broader speculation around quantum mechanics. Even without parallel universes, quantum computing is a monumental step forward in our understanding of computation and the physical universe.
A Quantum Leap with Questions
Google’s claim about Willow and the multiverse is undoubtedly bold, but it’s also grounded in cutting-edge science that pushes the boundaries of what we know. While the practical applications of quantum computing are still years, if not decades, away, Willow is a glimpse into a future where the impossible may become routine.
Whether or not the multiverse is involved, one thing is certain: quantum computing is opening doors to possibilities we’ve only just begun to imagine.
