Konrad Zuse, Who Built The First Programmable Computer And Then Argued The Universe Is One

Key Takeaways The Z3 claim needs every one of its qualifiers. It was the first programmable, automatic, digital computer that worked. It was not electronic, it did not store its program in memory, and it had no way to branch. He raised the quantum objection against himself. Calculating Space says in its own pages that a model behaving according to quantum physics would be extremely difficult to build. Summaries that present him as having answered it are overstating his case. He also guessed the symmetry objection, decades early. Zuse wrote that a grid structure would abolish the isotropy of space and would be hard to reconcile with relativity. Fritz in 2013 and Hossenfelder in 2015 proved him right. Bell tests rule out the classical version. A deterministic classical cellular automaton is a local hidden-variable theory, and loophole-free experiments since 2015 have closed that door. The surviving route runs through qubits, not bits. Quantum cellular automata are discrete and local without being hidden-variable theories. That saves the idea and concedes the original point. Plankalkuel was compiled in his lifetime. Joachim Hohmann built a compiler in a 1975 dissertation, twenty years before Zuse died. What is true is that it never ran on one of his own machines. On This Page The engineer who wanted to stop doing arithmetic The Z1, the Z3 and what the word first is worth What the war took, and what Zuse built for it Plankalkuel, a language with nowhere to run Zuse KG, 251 machines and a sale to Siemens Rechnender Raum, and what Zuse actually argued Where Zuse got stuck, and knew it Who picked the idea up What physicists say now What is left Frequently asked questions Konrad Zuse was a German civil engineer who built the Z3 in wartime Berlin, the first working programmable automatic computer, and later argued that the universe is itself a computation. The second claim is the one that has outlived him. He made it in a short book called Rechnender Raum, published in 1969

Scientists are building a microscope powered by a quantum computer - Science Daily

Science News from research organizations Scientists are building a microscope powered by a quantum computer Date: September 13, 2026 Source: Universität Wien Summary: Scientists are combining an electron microscope with a quantum computer to squeeze far more information from each electron. The approach could reveal faint details with fewer electrons, helping protect fragile samples that conventional microscopy can damage. Share: Facebook Twitter Pinterest LinkedIN Email FULL STORY An electron microscope capable of performing quantum computing operations using built-in ion traps. Credit: TU Wien Electron microscopes can reveal structures far smaller than anything visible with ordinary light. But researchers in Austria say conventional electron microscopes may be leaving valuable information on the table. In a standard system, electrons are mainly counted to build an image. Yet each electron also carries quantum information that normally goes unused. Researchers at TU Wien, working with teams from the University of Vienna, JKU Linz and the University of Innsbruck, have developed a new approach designed to capture and process some of that extra information. Their idea is to connect an electron microscope to a quantum computer. By doing so, the researchers hope to extract more useful information from each electron, potentially allowing scientists to form clearer images while exposing delicate samples to fewer electrons. That could be especially valuable for biological materials that are easily damaged. A quantum computer electron microscope based on the concept is now being constructed at TU Wien. Using Quantum Entanglement to Get More From Each Electron Modern electron microscopes already achieve extraordinary resolution. "Today, we can image tiny details on the atomic scale," says Philipp Haslinger from the Institute of Atomic and Subatomic Physics at TU Wien. "However, this requires a large number of electrons. And not every sample can be exposed to so many electrons

Physicists discover a hidden “curveball” in quantum light - Science Daily

Science News from research organizations Physicists discover a hidden “curveball” in quantum light Date: September 13, 2026 Source: Paul Scherrer Institute Summary: Researchers have experimentally demonstrated the optical Magnus effect for the first time, revealing that a tightly focused laser interacts most strongly with an atom slightly away from the beam’s center. The unexpected shift is similar to the physics that makes a spinning table tennis ball curve through the air. Because lasers are used to control qubits, the effect could create errors in quantum computers, but it might also provide a new way to couple qubits together. Share: Facebook Twitter Pinterest LinkedIN Email FULL STORY Putting spin on a ping-pong ball changes its trajectory – a similar effect also occurs in the quantum world. Credit: AI-generated symbolic image, Paul Scherrer Institute Table tennis players can make a ball suddenly curve by giving it just the right spin. That motion is caused by the Magnus effect, a familiar piece of physics that also influences the flight of larger balls in sports such as soccer. Now, an international team working at the Paul Scherrer Institute PSI has observed a related effect at the atomic scale. For the first time, researchers have experimentally demonstrated the optical Magnus effect by focusing laser light on a single ion and measuring how the light interacts with it. Instead of causing an atom to follow a curved path, the effect shifts the location where the laser interacts most strongly with the ion. That interaction point moves slightly sideways, a finding that could matter for quantum computers that use laser light to control qubits with extreme precision. The results were published in Physical Review Letters. A Laser's Strongest Interaction Is Slightly Off Center At first glance, it seems reasonable to expect that an ion would interact most strongly with a laser exactly at the beam's brightest point. But when laser light is focused very tightly, the st
