E6 was formed in 1947 to address the indus­tri­al mar­ket for machin­ing with nat­ur­al dia­mond. Since then E6 has become the world leader in the pro­duc­tion of all forms of man-made dia­mond for indus­tri­al appli­ca­tions and has pio­neered the devel­op­ment of Chem­i­cal Vapour Depo­si­tion (CVD) dia­mond syn­the­sis tech­nol­o­gy and mate­ri­als since the 1980s. E6 is cur­rent­ly the lead­ing sup­pli­er of sin­gle crys­tal and poly­crys­talline CVD dia­mond prod­ucts (exam­ples include laser exit win­dows, cut­ting tools, domed dia­mond for use in high-end speak­ers, win­dows for high-pow­er gyro­trons, heat-spread­ers for elec­tron­ic devices and high-puri­ty elec­tron­ic-grade dia­mond). In con­junc­tion to E6’s facil­i­ties that man­u­fac­ture these prod­ucts they also have a world- renowned dia­mond inno­va­tion site based in Har­well, UK where their R&D efforts are con­cen­trat­ed.
E6 has a track record in work­ing with world-lead­ing aca­d­e­m­ic groups pro­gress­ing quan­tum appli­ca­tions in dia­mond. Dur­ing these col­lab­o­ra­tive efforts quan­tum-grade dia­mond has been devel­oped and this has enabled state-of-the-art room-tem­per­a­ture coher­ence times to be achieved for sol­id-state qubits.
