Imagine a future where your doctor doesn’t just run a blood test or scan to see if something’s wrong. Instead, they could zoom into your individual cells and watch them in action — almost like monitoring a movie playing at the microscopic level. Even better, they might catch diseases right as they’re starting, long before symptoms show up.
Sounds like science fiction? Well, scientists at the University of Chicago may have taken a baby step in that direction. Their recent research suggests that certain proteins inside our cells can behave a little like qubits — the building blocks of quantum computers.
That’s right: the same kind of physics that powers futuristic machines in high-tech labs could also exist inside living, breathing cells.
Why This Is a Big Deal
Let’s pause for a second. Normally, biology and quantum mechanics don’t mix well. Quantum computers are incredibly fragile. Qubits — unlike the simple 1s and 0s used in classical computers — can exist in a strange state called superposition, meaning they can be both “on” and “off” at the same time. This is what gives quantum machines their almost magical computing power.
But here’s the catch: qubits are extremely picky. They usually need carefully controlled environments, with almost no noise or interference. Even tiny vibrations or stray energy can ruin their state. That’s why most quantum computers are locked in super-cooled labs, shielded from the outside world.
Cells, on the other hand, are anything but quiet. Inside them, enzymes are buzzing, proteins are folding, molecules are bumping into each other, and organelles are shuttling around like commuters in rush hour. It’s chaos compared to the delicately balanced world qubits usually require.
So how could a cell — the biological equivalent of a bustling city — ever host something as finicky as a qubit?

The Chicago Twist
Here’s where the cleverness comes in. The University of Chicago team decided to use fluorescent proteins, a class of proteins that naturally glow under certain conditions. These proteins are already used by scientists to light up cells like neon signs, helping them track gene expression or protein activity.
One protein in particular stood out: enhanced yellow fluorescent protein (EYFP). Researchers have used EYFP for decades to study biology, but this time, they looked at it from a quantum perspective.
It turns out EYFP has a special “triplet state.” That’s science-speak for when two electrons inside the protein line up their spins in parallel, even while sitting in different orbits. This odd alignment gives EYFP a kind of stability that most proteins lack — stability that just might allow it to behave like a qubit.
Turning a Protein Into a Qubit
So how do you make a biological qubit? The researchers engineered fluorescent proteins to match certain cellular proteins. Then they paired them with “mirror proteins” and zapped them with ultrafast laser pulses.
These pulses nudged the electrons into superposition, the hallmark of qubits. Suddenly, the protein wasn’t just glowing — it was acting as a tiny quantum probe.
The beauty of this setup is that when the qubit’s superposition is disturbed, the disturbance leaves behind a signature. That “signature” tells scientists about what’s happening around the protein, from normal cellular processes to early signs of genetic mutations. In other words, these protein-based qubits don’t just sit around looking pretty — they encode information about the cell’s inner workings.
What This Could Mean
The implications are fascinating. If you can tag a specific protein in a cell with a qubit, you can effectively watch that protein in real-time. Imagine seeing how a cancer-causing mutation first changes cell behavior, or how neurons respond at the molecular level to new drugs.
This isn’t just about medicine, either. The researchers suggest that protein-based qubits could also teach us more about the physics of qubits themselves. Biology might offer tricks that pure physics labs haven’t discovered yet. As they put it, this crossover between bioengineering and quantum information science has “transformative possibilities.”

From Jellyfish Glow to Quantum Glow
Here’s a fun connection: fluorescent proteins like EYFP originally came from jellyfish. In the 1960s, scientists discovered green fluorescent protein (GFP) in jellyfish and later adapted it as a universal biological marker. Since then, glowing proteins have revolutionized biology, even earning their discoverers a Nobel Prize in 2008.
Now, decades later, we’ve gone from using these proteins as colorful tags in biology labs to reimagining them as quantum sensors. It’s almost poetic — jellyfish glow helping us peer into the quantum world inside our own cells.
Quantum Biology Isn’t Entirely New
If all this sounds a bit wild, it’s worth noting that quantum effects have long been suspected in biology. For instance:
- Photosynthesis: Some studies suggest that plants may use quantum superposition to move energy around their cells more efficiently.
- Bird Navigation: Certain migratory birds might sense Earth’s magnetic field using quantum entanglement in proteins within their eyes.
- Olfaction (Smell): There are even theories that our ability to smell might involve quantum tunneling, where electrons “jump” through energy barriers.
So the idea that proteins could host qubit-like behavior isn’t as alien as it sounds. It’s part of a growing field sometimes called quantum biology, where the weirdness of quantum physics overlaps with the complexity of life.
What’s Next?
Right now, this research is still very experimental. Turning proteins into reliable qubits isn’t something you’ll see in a hospital anytime soon. But the potential is enormous:
- Medical Diagnostics: Instead of waiting for visible symptoms or broad tests, doctors could monitor disease at the level of individual proteins.
- Drug Development: Pharmaceutical companies could observe in real time how new drugs interact with specific cellular targets.
- Physics Insights: Protein qubits could uncover new principles of quantum behavior that might feed back into designing better quantum computers.
Of course, there are challenges. Engineering proteins to behave consistently, keeping them stable in messy biological environments, and scaling up the technology are all hurdles. But even the possibility that cells could double as quantum sensors is enough to make both biologists and physicists sit up straighter.

The Takeaway
The University of Chicago team may not have turned cells into full-fledged quantum computers, but they’ve shown that proteins can mimic some of the most intriguing behaviors of qubits. It’s a strange, almost whimsical marriage of physics and biology — one where glowing proteins could help us peek into the deepest secrets of life itself.
And who knows? Someday, when you go for a checkup, your doctor’s diagnostic tools might owe as much to quantum physics as they do to traditional biology. Until then, we can marvel at how jellyfish-inspired proteins might hold the keys to both healthier humans and smarter computers.
