Treating the infinite-dimensional Hilbert space of non-Abelian gauge theories is an
outstanding challenge for classical and quantum simulations. Here, we employ q-deformed …

Quantum-computation architecture based on d-level systems, or qudits, has attracted
considerable attention recently due to their enlarged Hilbert space. Extensive theoretical …

Efficient scaling and flexible control are key aspects of useful quantum computing hardware.
Spins in semiconductors combine quantum information processing with electrons, holes or …

Gate-based quantum computers typically encode and process information in two-
dimensional units called qubits. Using d-dimensional qudits instead may offer intrinsic …

Using quantum systems with more than two levels, or qudits, can scale the computational
space of quantum processors more efficiently than using qubits, which may offer an easier …

High-dimensional quantum information processing has emerged as a promising avenue to
transcend hardware limitations and advance the frontiers of quantum technologies …

Gate-based quantum computation has been extensively investigated using quantum circuits
