This study definitively resolves a long-standing theoretical question by proving that fourteen states constitute the minimum cardinality for a genuinely unextendible product basis in a three-qutrit system. The construction extends to all tripartite systems with local dimensions of at least three, advancing fundamental understanding within quantum information theory. This result provides essential structural insights relevant to future developments in quantum protocols and error correction schemes.

Researchers Find Minimum Size for Quantum Basis

Quantum ZeitgeistAugust 17, 20264 min read

A genuinely unextendible product basis with precisely fourteen elements now exists, definitively resolving a long-standing question in quantum information theory. Prior work established a lower bound of thirteen states, but this construction proves fourteen is the minimum cardinality for a three-qutrit system. This result extends to all tripartite systems utilising local dimensions of at least three.

A genuinely unextendible product basis now exists, confirmed by the construction of a three-qutrit basis with a cardinality of fourteen. This confirms its existence within the smallest possible three-part quantum system, a tripartite Hilbert space. The team, led by Fei Shi of the Sun Yat-sen University and colleagues from University of Science and Technology of China and The University of Hong Kong, proved that fourteen is the minimum number of states required for such a basis.…
