	abstract = {We resolve the host galaxies of seven gravitationally lensed quasars at 
redshift 1.5 to 2.8 using observations with the Atacama Large
(sub-)Millimetre Array. Using a visibility-plane lens modelling
technique, we create pixellated reconstructions of the dust morphology,
and CO line morphology and kinematics. We find that the quasar hosts in
our sample can be distinguished into two types: 1) galaxies
characterised by clumpy, extended dust distributions (\$R\_\{{\textbackslash}rm eff\}{\textbackslash}sim2\$
kpc) and mean star formation rate surface densities comparable to
sub-mm-selected dusty star-forming galaxies (\${\textbackslash}Sigma\_\{{\textbackslash}rm SFR\}{\textbackslash}sim5\$
M\$\_\{{\textbackslash}odot\}\$ yr\${\textasciicircum}\{-1\}\$ kpc\${\textasciicircum}\{-2\}\$); 2) galaxies that have sizes in dust
emission similar to coeval passive galaxies and compact starbursts
(\$R\_\{{\textbackslash}rm eff\}{\textbackslash}sim0.5\$ kpc), with high mean star formation rate surface
densities (\${\textbackslash}Sigma\_\{{\textbackslash}rm SFR\}=\$ 40\$-\$2200 M\$\_\{{\textbackslash}odot\}\$ yr\${\textasciicircum}\{-1\}\$
kpc\${\textasciicircum}\{-2\}\$) and peak densities of 280\$-\$3700 M\$\_\{{\textbackslash}odot\}\$ yr\${\textasciicircum}\{-1\}\$
kpc\${\textasciicircum}\{-2\}\$ that in some cases are Eddington-limited. The small size of
some quasar hosts suggests that we observe them at a stage in their
transformation into compact spheroids, where a high density of
dynamically unstable gas leads to efficient star formation and black
hole accretion. For the one system where we probe the mass of the gas
reservoir, we find a gas fraction of just \$0.06 {\textbackslash}pm 0.04\$ and a
depletion timescale of \$50 {\textbackslash}pm 40\$ Myr, suggesting it is transitioning
into quiescence. In general, we expect that the extreme level of star
formation in the compact quasar host galaxies will rapidly exhaust their
gas reservoirs and could quench with or without help from active
galactic nuclei feedback.},
