Quantum 9, 1607 (2025). https://doi.org/10.22331/q-2025-01-23-1607 We investigate mixed states exhibiting nontrivial topological features, focusing on symmetry-protected topological (SPT) phases under various types of decoherence. Our findings demonstrate that these systems can retain topological information from […]
The future of tin-based qubits is brighter thanks to breakthrough work by Stanford University researchers. Qubits are the fundamental carriers of quantum information, and scientists worldwide are engineering atoms to create reliable, long-lived qubits for […]
Insider Brief D-Wave Quantum Inc. announced the completion of its $150 million “at-the-market” equity offering program, raising funds to support technical development and business operations. The program, completed at an average share price of $6.10, […]
Calculus is a powerful mathematical tool. But for hundreds of years after its invention in the 17th century, it stood on a shaky foundation. Its core concepts were rooted in intuition and informal arguments, rather […]
Quantum 9, 1606 (2025). https://doi.org/10.22331/q-2025-01-23-1606 Quantum learning tasks often leverage randomly sampled quantum circuits to characterize unknown systems. An efficient approach known as “circuit reusing,” where each circuit is executed multiple times, reduces the cost […]
In the first study of its kind at the Large Hadron Collider (LHC), the CMS collaboration has tested whether top quarks adhere to Einstein’s special theory of relativity. The research is published in the journal […]
Researchers at the University of Basel have shown that quantum systems can have antagonistic interactions, too—one agent attracts the other, but the other way around, there is a repulsion. Such interactions could be realized using […]
Quantum entanglement—a phenomenon where particles are mysteriously linked no matter how far apart they are—presents a long-standing challenge in the physical world, particularly in understanding its behavior within complex quantum systems. Click to rate this […]
Insider Brief: IonQ and the Busan Metropolitan Government signed an MOU to collaborate on nurturing talent and advancing quantum technology in South Korea, positioning Busan as a global quantum computing hub. IonQ will provide quantum […]
Quantum computers have the potential of outperforming classical computers on some optimization tasks. Yet scaling up quantum computers leveraging existing fabrication processes while also maintaining good performances and energy-efficiencies has so far proved challenging, which […]
