Quantum Gold Rush: QUBT vs. D-Wave – Inside the High-Stakes 2025 Quantum Computing Showdown

In-Depth Report Company Overviews & Quantum Approaches Quantum Computing Inc. (QUBT) – Photonic Quantum Tech at Room Temperature: Quantum Computing Inc., branded as QCi, is a small-cap quantum technology company that has captured outsized attention due to its unconventional approach. Rather than using superconducting circuits or ion traps like many competitors, QCi focuses on photonic quantum computing – using particles of light (photons) passing through specialized optical chips to perform computations. The company’s core technology revolves around thin-film lithium niobate (TFLN) photonic integrated circuits nasdaq.com. This approach potentially offers a big advantage: QCi’s photonic qubits can operate at ambient room

Quantum Leap: Why IonQ, Rigetti, and D-Wave Stocks Are Soaring in a Tech Breakout

Introduction: A Quantum Stock Boom Not long ago, quantum computing felt like science fiction. Today, it’s driving some of the stock market’s most explosive rallies. Over the past year, shares of the leading pure-play quantum computing companies have skyrocketed, far outpacing even other hot tech sectors. D-Wave Quantum (NYSE: QBTS) surged +2,158%, Rigetti Computing (Nasdaq: RGTI) jumped +2,448%, and IonQ (NYSE: IONQ) climbed +705% in just 12 months fastcompany.com. By comparison, even the electric vehicle and AI stock frenzies didn’t produce such across-the-board gains. This “quantum boom” has pushed the trio – sometimes dubbed the “Quantum Four” along with smaller

Mining the Moon’s Helium-3: The Key to a Quantum Computing and Energy Revolution

Mining the Moon’s Helium-3: The Key to a Quantum Computing and Energy Revolution

What Is Helium-3 and Why Is It So Important? Infographic: Helium-3 is continually generated by fusion reactions in the Sun and carried by the solar wind. The Moon, lacking a magnetic field, has absorbed this isotope for billions of years, whereas Earth’s magnetic field shields us from most Helium-3 interlune.space. Helium-3 (He-3) is a lightweight, non-radioactive isotope of helium with two protons and one neutron (regular helium-4 has two neutrons). On Earth it is extremely scarce – mostly a byproduct from the decay of tritium in nuclear weapons and reactors sciencefocus.com. In total, only a few dozen kilograms are produced

Quantum Revolution 2025: Unhackable Encryption, Superspeed Computing & the 6G Quantum Future

Post-Quantum Cryptography: Securing the Internet Against Quantum Attacks In 2025, the race is on to rebuild our digital security before quantum computers can crack it. Modern encryption protocols like RSA and ECC – which protect everything from online banking to emails – could be rendered obsolete by a powerful quantum computer running Shor’s algorithm. Post-quantum cryptography (PQC) refers to new cryptographic algorithms designed to resist quantum attacks while still running on conventional computers csrc.nist.gov csrc.nist.gov. After a 7-year global competition, the U.S. National Institute of Standards and Technology (NIST) finalized its first PQC standards in August 2024 nist.gov. These include

Quantum Frenzy: Historic Breakthroughs & Bold Moves Unveiled in 48 Hours

Scientific Breakthroughs Spark a Quantum Leap Quantum Internet Node: In a breakthrough for quantum communication, researchers at the University of Innsbruck demonstrated a scalable quantum network node that connects trapped-ion qubits with photons sciencedaily.com. Using a string of calcium ions as qubits, the team moved each ion into an optical cavity and triggered it with a laser to emit a single entangled photon linked to that ion’s quantum state sciencedaily.com. By repeating this for ten ions, they generated a stream of entangled photons ready to carry quantum information to other nodes. The Innsbruck prototype achieved a high entanglement fidelity of
