Temporal fusion of entangled resource states from a quantum emitter
Experimental scheme
The experimental setup is outlined in Fig. 2a. It consists of a resource state generator chip, an active switch for routing photons from the emitted resource states, and a fiber-based temporal fusion gate via fiber delay and…

Compromise-free scaling of qubit speed and coherence
Coherent spin control at 1.5 K
We first demonstrate the operation of our Ge/Si NW hole spin qubit at 1.5 K, adding it to the list of previously demonstrated hot qubits9,10,11,12. A scanning electron micrograph showing a representative device…

Entanglement and the density matrix renormalization group in the generalized Landau paradigm
Dualities
We explain here how to obtain the models dual to equation (1) considered in the main text. We encourage the reader to consult ref. 48 for further details. First, it is crucial to rewrite the local operators entering the definition of the…

Network dismantling by physical damage
Random damage
In this section, we explore the effect of the combinatorial network \({{{\mathcal{G}}}}\) and the layout \({{{\mathcal{P}}}}\) on the physical percolation of randomly embedded networks. Figure 2 shows the relative size S of the…

New precise solitary wave solutions for coupled Higgs field equations via two enhanced methods
In this section, the ESSM49 is employed to address the CHFE, resulting in various solutions for solitary waves including exponential, trigonometric, and hyperbolic forms. The wave transformation will be conducted as follows:
$$u(x,t) = U(\xi…

Reducing the Number of Wires on a Quantum Chip
• Physics 18, s110
Experiments show that one of the standard electrode types for semiconductor-based quantum processors isn’t needed.
Tapping into computer-chip technology is one of the advantages to building a…
