      abstract     = {Semiconductor spins are one of the few qubit realizations
                      that remain a serious candidate for the implementation of
                      large-scale quantum circuits. Excellent scalability is often
                      argued for spin qubits defined by lithography and controlled
                      via electrical signals, based on the success of conventional
                      semiconductor integrated circuits. However, the wiring and
                      interconnect requirements for quantum circuits are
                      completely different from those for classical circuits, as
                      individual direct current, pulsed and in some cases
                      microwave control signals need to be routed from external
                      sources to every qubit. This is further complicated by the
                      requirement that these spin qubits currently operate at
                      temperatures below 100 mK. Here, we review several
                      strategies that are considered to address this crucial
                      challenge in scaling quantum circuits based on electron spin
                      qubits. Key assets of spin qubits include the potential to
                      operate at 1 to 4 K, the high density of quantum dots or
                      donors combined with possibilities to space them apart as
                      needed, the extremely long-spin coherence times, and the
                      rich options for integration with classical electronics
                      based on the same technology.},
