Scalability is becoming an increasingly important metric against which to assess the suitability of qubit candidates for large scale quantum computing implementations. Spin qubits, specifically electron spins in silicon quantum dots, are often considered a highly scalable candidate due to their inherent similarities to transistors. However, complications arise when considering the need for...
Future quantum computers capable of solving relevant problems will require a large number of qubits that can be operated reliably[1]. However, the requirements of having a large qubit count and operating with high-fidelity are typically conflicting. Spins in semiconductor quantum dots show long-term promise but demonstrations so far use between one and four qubits and typically optimize the...
