                  method in which the test outcomes represent bounded
                  intervals for the number of defectives.
                  Alternatively, it may be viewed as an adder channel
                  with quantized outputs. SQGT represents a natural
                  choice for Covid-19 group testing as it allows for a
                  straightforward interpretation of the cycle
                  threshold values produced by polymerase chain
                  reactions (PCR). Prior work on SQGT did not address
                  the need for adaptive testing with a small number of
                  rounds as required in practice.  We propose
                  conceptually simple methods for $2$-round and
                  nonadaptive SQGT that significantly improve upon
                  existing schemes by using ideas on nonbinary
                  measurement matrices based on expander graphs and
                  list-disjunct matrices.}
