Serge Haroche

1944–present · quantum optics, atomic physics, quantum measurements
French physicist, one of the creators of cavity QED (electrodynamics of resonators). He studies the interaction of single atoms with photons in superconducting cavities, observes quantum decoherence, and implements non-destructive quantum measurements. Nobel Prize laureate in 2012.

Biography

Born in Casablanca, Morocco. PhD from Pierre and Marie Curie University in Paris. Professor at the Collège de France and École Normale Supérieure. Together with Jean-Michel Raimond, he built a unique experimental setup that allows 'counting' photons without absorbing them.

Key discoveries

💡 His resonator experiment can be compared to 'counting photons without turning on the light'; it literally allows one to see quantum superposition and its collapse.
"He viewed the boundary between the quantum and classical worlds not as a wall but as a bridge that humanity is only learning to cross."

How to Squeeze Light Through a Needle's Eye and Keep It from Spreading
Shine a flashlight through a narrow slit, and the beam doesn't stay a thin stripe; it spreads out sideways. Light has a habit of bending around obstacles, and because of that, the smallest spot you can get with an ordinary lens is no smaller than half a wavelength.

Two Horizons, One Thermometer: How Quantum Fields Erase Temperature Differences
Two vessels of water at different temperatures are separated by a thin partition. As long as the partition is intact, each vessel lives its own life: in one, the water is hot; in the other, it's icy. But once the partition is removed, the temperatures begin to equalize, and eventually both vessels reach the same state.

Getting the Most Out of Every Photon
A fluorescence microscope is like a photographer shooting in the dark: the more frames, the better the view, but each frame costs photons. In a living cell, the supply is limited, otherwise the light would simply kill the sample. So scientists proposed not to increase the number of photons, but to choose more wisely when to catch them.

Light from Within: How to See 12 Centimeters Deep into the Body
Light is a great tool for studying tissues, but it fades fast deep inside the body. Within a few millimeters, photons scatter so much that you can't make out anything. Scientists came up with a workaround: instead of shining light from outside, deliver a tiny light source right inside. The challenge is how to power that source without wires.

Peering into Tight Spots: A Fiber Thinner Than a Hair

A Whole Object in a Single Flash
As light passes through a patterned plate, it folds inside a transparent liquid into a three-dimensional pattern. Where the light is brighter, the resin hardens. After 7.5 seconds, a finished part is lifted out of the liquid — complete with cavities, channels, and tiny protrusions. A regular 3D printer prints point by point or layer by layer.

A Needle That Sees Through Tight Spaces
Light aimed at a metal needle typically scatters sideways, and only a small fraction collects at the very tip. To squeeze it into a spot just a few atoms across, microscope optics are made expensive and bulky, and the distance to the sample becomes tiny. The new work proposes a tip that focuses light on its point by itself, like a funnel gathering rainwater into a narrow neck.

How Silver Particles Grow: A Movie from an Atomic Microscope

Light That Corrects Itself
A photo taken through frosted glass always comes out blurry. As light passes through a sample, it scatters, and the camera sees only a smudge instead of a sharp image. Scientists have long known how to recover an image from such a smudge, but old methods are finicky: they either get stuck on a wrong solution or require too many exposures, bombarding the fragile sample.

Printing with Light: a Million Voxels per Second
A typical 3D printer squeezes out plastic like a pastry chef piping cream from a bag. Here, instead of plastic, it's light. A laser beam draws in liquid resin, making it solidify at precise points. This creates parts too small to see without a microscope. Until now, such printers were slow: the beam crawled across the surface like a pen on paper.

Seeing Heat: How a Camera Captures Invisible Light
A warm cup or a human hand emits invisible light — mid-infrared radiation. Every substance absorbs this light in its own way, leaving a unique 'fingerprint'. From this fingerprint, you can tell what an object is made of without touching it. Previously, seeing this fingerprint required huge lasers that fired very short pulses. They were expensive and complex.
